Question

(x − 3) − (x + 2) + 2(x − 1) − 5 = 0


ajudemmm​

Answer 1

Resposta: (x − 3) − (x + 2) + 2(x − 1) − 5 = 0, ou seja x=6

Explicação passo-a-passo:

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

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

2x-5-7=0

2x=7+5

2x=12

x=12/2

x=6

Answer 2

$x - 3 - x - 2 + 2x -2 - 5 = 0 \\ 2x - 12 = 0 \\ 2 x = 12 \\ x = \frac{12}{2} \\ x = 6$
