Question

Resolva as equação de 1 grau :
A)5.(x+3)=2.x

B) 3.(4x-2)=5.(2.x+3)+3

C) 3.(4.x-2)=5.(2.x+3)+3

Answer 1

Resposta:

Explicação passo a passo:

A) 5(x+3) = 2x

5x+15 = 2x

5x-2x=-5

3x=-5

x=-5

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

12x - 6 = 10x +15 +3

12x-10x=15+3+6

2x=22

x=11

C) 3(4X-2)=5(2X+3)+3

12x - 6 = 10x +15 +3

12x-10x=15+3+6

2x=22

x=11
