Question

1) Encontre o valor de x: 3(x-1) +2 = 2 (x +1) -5

Answer 1

$\sf3(x-1)+2=2(x+1)-5$

$\sf3x-3+2=2x+2-5$

$\sf3x-3=2x-5$

$\sf3x-2x=-5+3$

$\boxed{\boxed{\sf x=-2}}$

Answer 2

Resposta: x = -2

Explicação passo a passo:

3(x-1) + 2 = 2(x+1) - 5

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

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

x = -3 + 1

x = -2
