Question

8x+5=0
3x-7=2
11-4x=2x

Answer 1

8x = -5         3x = 2+7         11 = 2x + 4x
x = -5/8         3x = 9              11 = 6x
x = -0.625          x=3                  11/6 = x

Answer 2

$1)~~8x+5=0 \ 8x=-5 \ x=-0,625 \ \2)~~ 3x-7=2 \ 3x=9 \ x=3 \ \3)~~ 11-4x=2x \ 6x=11 \ x= frac{11}{6} \ ~~x=1 frac{5}{6}$
