Question

$10 - 3(x + 2) = 5x - 4$
​

Answer 1

Resposta:

-9

Explicação passo-a-passo:

10 - 3(x + 2) = 5x - 4

7(x + 2) = 5x - 4

7x + 14 = 5x - 4

7x - 5x = -4 - 14

2x = -18

x = -18/2

x = -9

Answer 2

Resposta:

$10 - 3(x + 2) = 5x - 4 \\ 10 - 3x - 6 = 5x - 4 \\ - 3x + 4 = 5x - 4 \\ - 3x - 5x = - 4 - 4 \\ - 8x = - 8 \\ 8x = 8 \\ x = 8 \div 8 \\ x = 1$
