Question

Resolva:

2x +3 x +9=48-8x?
2x+5x=7?
x+28=11?
2x/3= -10?

​

Answer 1

Resposta:

x = 3

x = 1

x = -17

x = -15

Explicação passo a passo:

2x + 3 x + 9 = 48 - 8x

5x + 8x = 48 - 9

13x = 39

x = 39/13

x = 3

2x + 5x = 7

7x = 7

x = 7/7

x = 1

x + 28 = 11

x = 11 - 28

x = -17

2x / 3 = -10

2x = -10 . 3

2x = -30

x = -30/2

x = -15
