Question

9×+2.(2×-18)=2.(5×+12)​

Answer 1

9x + 2(2x - 18) = 2(5x + 12)

9x + 4x - 36 = 10x + 24

13x - 10x = 24 + 36

3x = 60

x = 60 / 3

x = 20

Answer 2

Explicação passo a passo: 9x + 2(2x - 18) = 2(5x + 12)

9x + 4x - 36 = 2(5x + 12)

9x + 4x - 36 = 10x + 24

13x - 36 = 10x + 24

13x - 10x - 36 = 24

13x - 10x = 24 + 36

3x = 24 + 36

3x = 60

x = 60 ÷ 3 ou x = 60/3

x = 20

Espero ter ajudado!
