Answer:
x = -10
Step-by-step explanation:
I will assume that you meant:
(1/4)(8x-20)=6x - (x-25) = 5x + 25
If this is correct, let's remove the denominator 4 by multiplying all terms by 4:
(8x - 20) = 4(6x - x + 25), or
8x - 20 = 20x + 100
Consolidating the x terms on the right and the constants on the left, we get:
-120 = 12x, or x = -10
