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

Question

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

Answer 1

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
