Answer 1

Olá

$\LARGE{}(x - 3) - (x + 2) + 2(x - 1) - 5 = 0 \\ \LARGE{}x - 3 - (x + 2) + 2(x - 1) - 5 = 0 \\ \LARGE{}x - 3 - 2 + 2(x - 1) - 5 = 0 \\ \LARGE{}x - 3 - 2 + 2x - 2 - 5 = 0 \\ \LARGE{}\cancel{x} - 3 - \cancel{x} - 2 + 2x - 2 - 5 = 0 \\ \LARGE{} - 3 - 2 + 2x - 2 - 5 = 0 \\ \LARGE{} - 12 + 2x = 0 \\ \LARGE{}2x = 12 \\ \LARGE{}\LARGE\boxed{x = 6}$

Answer 2

Resposta:

x = 6

Explicação passo-a-passo:

(x - 3) - (x + 2) + 2×(x - 1) - 5 = 0

x - 3 - x - 2 + 2x - 2 - 5 = 0

x - x + 2x = 3 + 2 + 2 + 5

2x = 12

x = 12 ÷ 2

x = 6
