1/4 (8x-20) = 6x-1 (x-25)

x=-10

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
