Question

5(1- x) - 2x +1 = -3(2+x)​

Answer 1

Resposta:

x = 3

Explicação passo-a-passo:

$5(1 - x) - 2x + 1 = - 3(2 + x) \\ 5 - 5x - 2x + 1 = - 6 - 3x \\ 6 - 7x = - 6 - 3x \\ - 7x + 3x = - 6 - 6 \\ - 4x = - 12 \: \times ( - 1) \\ 4x = 12 \\ x = \frac{12}{4} \\ \bf{x = 3}$

Answer 2

5-5x-2x+1=-6-3x

-5x-2x+3x = -6-1-5

-4x = -12   x(-1)

4x = 12

x = 12:4

x=3
