You are going to distribute
-5(1-5x)+5(-8x-2)=-4x-8x
(-5*1) (-5*-5x)+(5*-8x)(5*-2)=4x-8x
-5 + 25x - 40x - 10 = 4x - 8x
~ Combine Like Terms ~
-5 + ( 25x - 40x ) - 10 = 4x - 8x
-5 + (-15x) - 10 = (4x - 8x)
-5 + (-15x) - 10 = -4x
~ Combine -5 and -10 ~
-5 - 10 - 15x = -4x
5 - 15x = -4x
~ Add 15x to each side combine it with its like term on the other side of the equal sign ~
5 - 15x = -4x
+15x +15x
___________
5 = 11x
We are going to divide to get the variable by itself
5 = 11x
__________
11x 11x
Your answer is (5/11)=x or 0.45 (repeating)= x
They are both the same answer just different ways to write it
