Question

resolva as equação

a) 2(X-1)-(X-1)=0

b) 5(X+1)-3(X+2)=0

Answer 1

a) 2x-2-x+1=0
x-1=0
x=0+1
x=1

b)5x+5-3x-6=0
2x-1=0
2x=0+1
2x=1
x=1/2

Espero ter ajudado, beijos. Thetheu! ;D

Answer 2

a) 2.(x - 1) - (x - 1) = 0 => 2.x - 2 - x + 1 = 0 => x - 1 = 0 => x = 1


b) 5.(x + 1) - 3.(x + 2) = 0 => 5.x + 5 - 3.x - 6 = 0 => 2.x - 1 = 0 => x = 1/2
