Question

2(x+5)-31=x+16+3(x-2)​

Answer 1

Resposta:

x = -31/2

Explicação passo-a-passo:

$2(x+5) - 31 = x + 16 + 3(x-2)$

$2x + 10 - 31 = x + 16 + 3(x-2)$

$2x + 10 - 31 = x + 16 + 3x - 6$

$2x - 21 = x + 16 + 3x - 6$

$2x - 21 =4x + 16 - 6$

$2x - 21 =4x + 10$

$2x - 21 - 4x = 10$

$-2x - 21 = 10$

$-2x = 10 + 21$

$-2x = 31$

$x = \dfrac{-31}{2}$
