Question

Resolva a equaçao do 1 grau
5.(2x-1)=2.(x+1)+5

Answer 1

$5(2x - 1) = 2(x + 1) + 5 \\ 10x - 5 = 2x + 2 + 5 \\ 10x - 2x = 2 + 5 + 5 \\ 8x = 12 \\ x = \frac{12}{8} \\ x = \frac{3}{2}$


S = {3/2}

Answer 2

Olá, boa noite ☺

Resolução:

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

10x - 5 = 2x + 2 + 5

10x - 2x = 2 + 5 + 5

8x = 12

x=12/8

Simplificando por 4

x = 3/2

Bons estudos :)
