Step-by-Step Solution

To solve this linear equation, we'll take the following steps:

  • Step 1: Multiply both sides of the equation by 2 to eliminate the fraction.
  • Step 2: Simplify and isolate the term containing x x .
  • Step 3: Solve for x x by further isolation.

Let's execute these steps:

Step 1: Start with the given equation:

5+7x2=22 \frac{-5 + 7x}{2} = 22

Multiply both sides by 2 to remove the fraction:

5+7x=44 -5 + 7x = 44

Step 2: Now, eliminate the constant term on the left side by adding 5 to both sides:

5+7x+5=44+5-5 + 7x + 5 = 44 + 5

This simplifies to:

7x=49 7x = 49

Step 3: Finally, solve for x x by dividing both sides by 7:

x=497 x = \frac{49}{7}

Calculate the result:

x=7 x = 7

Therefore, the value of x x is x=7 x = 7 .

Answer

7 7
