Question

me ajudem por favor

-8x + 10 = -2x + 2
2x + 12 = 14
3x/2 + x/4 = x + 3​

Answer 1

Resposta:

-8x + 10 = -2x + 2

-8x + 2x = +2 - 10

-6x = - 8  (x-1)

6x = 8

x = 8 / 6

2x + 12 = 14

2x = 14 - 12

2x = 2

x = 2/2 = 1

3x/2 + x/4 = x + 3​

3x + x - x = +3 . 2 . 4   (+ x - x = 0)

3x = 24

x = 24 / 3 = 8
