Let's simplify the equation step by step:

(7-10x) - (8-2x) - (10x-6) = -8

First, we distribute the negative sign in the second parentheses:

7 - 10x - 8 + 2x - 10x + 6 = -8

Now, combine like terms:

-18x + 5 = -8

Next, isolate the variable by moving the constant to the other side of the equation:

-18x = -13

Finally, solve for x by dividing both sides by -18:

x = -13 / -18
x = 13 / 18

Therefore, the solution to the equation is x = 13/18.
