x =11

Explanation:

3x - 5 = 11x - 93

3x -11x - 5 = - 93

3x -11x = - 93 + 5

-8x = - 88

cancel(-)8x = cancel(-) 88

8x =88

x =88 ÷ 8

color(blue)(x =11

Now we can substitute x for 11 to prove our answer.

3x - 5 = 11x - 93

3 xx 11 - 5 = 11 xx 11 - 93

33 - 5 = 121 - 93

28 = 121 - 93

121 - 93 = 28

28 = 28
