Step-by-step solution

To solve this problem, we'll proceed step-by-step:

First, we distribute the 12\frac{1}{2} across the term inside the parentheses:
12(10x15)=1210x1215 \frac{1}{2} \cdot (10x - \frac{1}{5}) = \frac{1}{2} \cdot 10x - \frac{1}{2} \cdot \frac{1}{5} .

This simplifies to:
5x110 5x - \frac{1}{10} .

Now, our equation becomes:
5x110=110+8x 5x - \frac{1}{10} = -\frac{1}{10} + 8x .

Next, we aim to gather the x x terms on one side. Subtract 5x 5x from both sides:
110=110+8x5x -\frac{1}{10} = -\frac{1}{10} + 8x - 5x .

Simplify the right-hand side:
110=110+3x -\frac{1}{10} = -\frac{1}{10} + 3x .

To isolate 3x 3x , subtract 110-\frac{1}{10} from both sides:
0=3x 0 = 3x .

Divide both sides by 3 to solve for x x :
x=0 x = 0 .

Therefore, the solution to the problem is x=0 x = 0 .
