$\Huge \sf 5.(x + 9) = 17 + 6x \dfrac {} {}\\\Huge \sf 5x + 45 = 17 + 6x \dfrac {} {}\\\Huge \sf 5x - 6x = 17 - 45 \dfrac {} {}\\\Huge \sf -x=-28 .(-1) \dfrac {} {}\\\Huge \sf x = 28 \dfrac {} {}$

Answer 2

Resposta:

x=28

Explicação passo-a-passo:

$5.(x + 9) = 17 + 6x \\ 5x + 45 = 17 + 6x \\ 5x - 6x = 17 - 45 \\ - x = - 28 \: \: \: \times ( = 1) \\ x = 28$
