Question

Como fasso ? 11x + 17 = 13x + 13

Answer 1

Resposta:

11x + 17 = 13x + 13

11x + 17 - 17 = 13x + 13 - 17

11x = 13x - 4

11x - 13x  = 13x - 4 - 13x

-2x = -4

-4/-2 = 2

x = 2

Answer 2

$11x + 17 = 13x + 13 \\ 11x - 13x = 13 - 17 \\ - 2x = - 4 \: .( - 1) \\ 2x = 4 \\ x = \frac{4}{2} \\ x = \boxed{2}$

espero ter ajudado!!!!
