D- 2x -6=2________________

20 pontosss preciso rápido por favor

Answer 1

Resposta:

Olá!!!

$x + 2 = 12 \\ x = - 2 + 12 \\ x = 10$

A)X=10

$3.x = 15 \\ 3x = 15 \\ x = 15 \div 3 \\ x = 5$

B)X=5

$5x - 2 = 8 \\ 5x = 8 + 2 \\ 5x = 10 \\ x = 10 \div 5 \\ x = 2$

C)X=2

$2x - 6 = 2 \\ 2x = 2 + 6 \\ 2x = 8 \\ x = 8 \div 2 \\ x = 4$

D)X=4
