Question

-5(2x+1)=-82+x calculo certinhos​

Answer 1

- 5 (2x + 1) = - 82 + x

- 10x - 5 = - 82 + x

- 10x - x = - 82 + 5

- 11x = - 77  * (-1)

11x = 77

x = 77 / 11

x = 7

Answer 2

Olá!

$- 5(2x + 1) = - 82 + x \\ - 10x - 5 = - 82 + x \\ - 10x - x = - 82 + 5 \\ - 11x = - 77 \: \times ( - 1) \\ 11x = 77 \\ x = \frac{77}{11} \\ \boxed{x = 7}$

Espero ter ajudado! :)
