Question

2•(x-2)-3•(1-x=20-(x-4)

Answer 1

$2(x - 2) - 3(1 - x) = 20 - (x - 4) \\ 2x - 4 - 3 + 3x = 20 - x + 4 \\ 2x + 3x + x = 20 + 4 + 4 + 3 \\ 6x = 31 \\ x = \frac{31}{6}$

Answer 2

Olá

2(x - 2) - 3(1 - x) = 20 - (x - 4)

2x - 4 - 3 + 3x = 20 - x + 4

2x + 3x + x = 20 + 4 + 3 + 4

6x = 31

x = 31/6

Resposta: x = 31/6

Espero ter ajudado.
