4x (2x+2) - (8x-1) (x+6) = 3

(8x^2+8x) - (8x^2+48x-x-6) = 3

(8x^2+8x) - (8x^2+47x-6) = 3

8x^2+8x-8x^2-47x+6=3

-39x=-3

x=3/39

x=1/13

(3-x) (4-8x) = x (1+8x)

12-24x-4x+8x^2=x+8x^2

12-28x+8x^2=x+8x^2

12-28x=x

29x=12

x=12/29

4x (2x+2) - (8x-1) (x+6) = 3(3-x) (4-8x) = x (1+8x)

4x (2x+2) - (8x-1) (x+6) = 3

(3-x) (4-8x) = x (1+8x)
