Equation (+ what is the unknown) - Examples, Exercises and Solutions

To solve the equation $5x = 0$ for $x$, we will use the following steps:

• Step 1: Identify that the equation is $5x = 0$.
• Step 2: To solve for $x$, divide both sides of the equation by 5.

Let's perform the calculation as outlined in Step 2:

$5x = 0$

Divide both sides by 5 to isolate $x$:

Simplifying, this gives:

$x = 0$

Therefore, the solution to the equation $5x = 0$ is $x = 0$.

The correct answer is option 4: $x = 0$.

To solve the equation $5x = 1$, we need to isolate $x$. Here are the steps:

• Step 1: Start with the equation $5x = 1$.
• Step 2: Divide both sides of the equation by the coefficient of $x$, which is 5, to isolate $x$. This gives us:
$\frac{5x}{5} = \frac{1}{5}$
• Step 3: Simplify the left side:
$\frac{5x}{5} = x$
• Step 4: Write the simplified equation:
$x = \frac{1}{5}$

Therefore, the solution to the equation $5x = 1$ is $x = \frac{1}{5}$.

The correct answer choice is:

$x = \frac{1}{5}$

The "absolute value" can be viewed as the distance of a number from 0.
Therefore, the absolute value will not change the sign from negative to positive, it will always be positive.

When we have an exercise with these symbols || we understand that it refers to absolute value.

Absolute value does not relate to whether a number is positive or negative, but rather checks how far it is from zero.

In other words, 2 is 2 units away from zero, and -2 is also 2 units away from zero,

Therefore, absolute value essentially "zeroes out" the negativity of the number.

|-2| = 2

These signs in the exercises refer to the concept of "absolute value",

In absolute value we don't have "negative" or "positive", instead we measure the distance from point 0,

In other words, we always "cancel out" the negative signs.

In this exercise, we'll change the minus to a plus sign, and simply remain with 19 and a quarter.

And that's the solution!

We are given the equation y=x

We are also given the value of x, 

x=2

Therefore, we will insert the given value into the equation

y=2

And that's the solution!

The absolute value of a number is the distance of the number from zero on a number line, without considering its direction. For the number $-25$, the absolute value is $25$ because it is 25 units away from zero without considering the negative sign.

The absolute value of a number is always non-negative because it represents the distance from zero. Therefore, the absolute value of $34$ is $34$.

The absolute value of a number is its distance from zero on the number line, without considering its direction. To find the absolute value of $5$, consider the distance of $5$ from zero, which is just $5$. Therefore, $\left|5\right| = 5$.

The absolute value of $0$ is the distance from zero to zero on the number line. Since zero is not negative or positive, $\left|0\right| = 0$.

The absolute value of a number is its distance from zero on the number line, regardless of the direction. To find the absolute value of $-7$, we need to look at the distance of $-7$ from zero, which is $7$. Therefore, $\left|-7\right| = 7$.

The absolute value of a number is the distance of the number from 0 on a number line, regardless of direction. Therefore, the absolute value of $-3.5$ is the same as moving 3.5 units away from 0, which results in $3.5$. Hence, $\left| -3.5 \right| = 3.5$.

The absolute value of a number is always its positive value. It represents the distance of the number from zero on the number line, regardless of direction. The absolute value of any negative number is its opposite positive number.

Step 1: Identify the number to find the absolute value of: $-7\frac{1}{2}$

Step 2: Change the negative sign to positive: $7\frac{1}{2}$

Hence, the absolute value of $-7\frac{1}{2}$ is $7\frac{1}{2}$.

The absolute value of a number is the positive form of that number, representing its distance from zero on the number line.

Step 1: Identify the number whose absolute value is needed: $-4\frac{3}{4}$

Step 2: Remove the negative sign from the number: $4\frac{3}{4}$

Thus, the absolute value of $-4\frac{3}{4}$ is $4\frac{3}{4}$.

To solve the equation $14x + 3 = 17$, we need to find the value of $x$ that satisfies the equation.

Step 1: Isolate the term containing $x$ by subtracting 3 from both sides of the equation:

$14x + 3 - 3 = 17 - 3$
This simplifies to:
$14x = 14$

Step 2: Solve for $x$ by dividing both sides by 14:

$x = \frac{14}{14}$
Which simplifies to:
$x = 1$

Therefore, the solution to the equation $14x + 3 = 17$ is $x = 1$.
