Question

5. (2x - 2) = 2. (x + 2)​

Answer 1

$5(2x - 2) = 2(x + 2) \\ 10x - 10 = 2x + 4 \\ 10x - 2x = 4 + 10 \\ 8x = 14 \\ x = \frac{14}{8} \\ x = \frac{7}{4}$

espero ter ajudado ;)

Answer 2

Resposta:

5 . 2x = 10x

5 . (-2) = -10

2 . x = 2x

2 . 2 = 4

10x - 10 = 2x + 4

10x - 2x = 4 +10

8x = 14

x = 14/8 (simplificando por 2)

x = 7/4
