Question

8(2x-1) = 6 (5x-2)-10 ?

Answer 1

8(2x-1)=6(5x-2)-10
16x-8=30x-12-10
16x-8=30x-22
16x-30x=-22+8
-14x=-14  (·-1)
14x=14
x=1

Answer 2

Temos que:

8(2x - 1) = 6(5x - 2) - 10
16x - 8 = 30x - 12 - 10
16x - 8 = 30x - 22
16x - 8 - 30x = 30x - 22 - 30x
- 14x - 8 = - 22
- 14x - 8 + 8 = - 22 + 8
- 14x = - 14
x = $\dfrac{-14}{-14}$
x = 1

Espero ter ajudado.
