Question

Resolva 4 ( x + 1 ) + 3 = 2 ( x - 1 ) + 5

me ajudemmmm​

Answer 1

4 ( x + 1 ) + 3 = 2 ( x - 1 ) + 5
4x + 4 + 3 = 2x - 2 + 5
4x - 2x = - 2 + 5 - 4 - 3
2x = 3 - 7
2x = - 4
x = - 4/2
x = - 2

Answer 2

Resposta: S=(-2)

Explicação passo-a-passo:

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

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

4x+4-2x+2=2

4x-2x=-2+2-4

2x=-4

x=-4/2

x=-2
