Step-by-Step Solution

To solve this problem, we will perform the following steps:

  • Step 1: Combine like terms on each side of the equation.
  • Step 2: Simplify the equation by performing arithmetic operations.
  • Step 3: Isolate the variable x x by using inverse operations to solve the equation.

Now, let's work through each step:

We start with the original equation:
1.716x+36x=3.5+212x 1.7 - \frac{1}{6}x + \frac{3}{6}x = 3.5 + \frac{2}{12}x

Step 1: Simplify both sides by combining like terms.
On the left side, combine the terms with x x :
36x16x=26x=13x \frac{3}{6}x - \frac{1}{6}x = \frac{2}{6}x = \frac{1}{3}x The equation becomes:
1.7+13x=3.5+212x 1.7 + \frac{1}{3}x = 3.5 + \frac{2}{12}x

Notice that 212x \frac{2}{12}x can be simplified to 16x \frac{1}{6}x

The equation is now:
1.7+13x=3.5+16x 1.7 + \frac{1}{3}x = 3.5 + \frac{1}{6}x

Step 2: To remove the fractions, find a common denominator for the coefficients of x x , which is 6. Convert 13x \frac{1}{3}x to a fraction with 6 as the denominator:
13x=26x \frac{1}{3}x = \frac{2}{6}x Substitute in the equation:
1.7+26x=3.5+16x 1.7 + \frac{2}{6}x = 3.5 + \frac{1}{6}x

Subtract 16x \frac{1}{6}x from both sides:
1.7+26x16x=3.5 1.7 + \frac{2}{6}x - \frac{1}{6}x = 3.5 This simplifies to:
1.7+16x=3.5 1.7 + \frac{1}{6}x = 3.5

Subtract 1.7 from both sides to isolate the term with x x :
16x=3.51.7 \frac{1}{6}x = 3.5 - 1.7 16x=1.8 \frac{1}{6}x = 1.8

Step 3: Solve for x x by multiplying both sides by 6 to clear the fraction:
x=1.8×6 x = 1.8 \times 6 Calculate the multiplication:
x=10.8 x = 10.8

Thus, the solution to the problem is x=10.8 x = 10.8 .

Answer

10.8 10.8
