Question

5(8x-1)-7(4x+1)=9-8(7-4x)

Answer 1

5(8x-1)-7(4x+1)=9-8(7-4x)
40x-5-28x-7=9-56+32x
12x-12=-47+32x
12x-32x=-47+12
-20x=-35
x=$\frac{-35}{-20}$ / :5
x=$\frac{7}{5}$

Answer 2

5(8x-1)-7(4x+1)=9-8(7-4x). 40x-5-28x-7=9-56+32 . 12x-12=32x-47. 12x-32x=-47+12. -20x=-35. x=-35 : (-20) \:5. x=-7 : (-4). x=1,75 COROANA ???
