Question

1)-3(x+1)+2=11
2)5(2x-1)=4x+11​

Answer 1

Explicação passo-a-passo:

$1) - 3.(x + 1) + 2 = 11 \\ - 3x - 3 + 2 = 11 \\ - 3x - 1 = 11 \\ - 3x = 11 + 1 \\ - 3x = 12 \: \: \times ( - 1) \\ 3x = - 12 \\ x = \frac{ - 12}{3}$

$x = - 4$

2)5(2x-1)=4x+11

10x-5=4x+11

10x-4x=11+5

6x=16

x=16/6

x=8/3
