Question

3(-9x-7)+12=10(x-10)-11

Answer 1

x = 2.75675675676

or in fractional form

x = 102/37

Explanation:

1) Expand the brackets

-27x-21+12 = 10x-100-11

2) Simplify further

-27x-9 = 10x-111

3) Add 27x on both sides

-9 = 37x-111

4) Add 111 on both sides

102 = 37x

5) Divide by 37 on both sides

102/37 = x
