Question

7x-6(x-19)=12x-21

:)​

Answer 1

Resposta:

x = 93

Explicação passo-a-passo:

$7x + 6(x - 19) = 12x - 21 \\ 7x + 6x - 114 = 12x - 21 \\ 7x + 6x - 12x = - 21 + 114 \\ x = 93$

Answer 2

x = 12, 27

Explicação passo-a-passo:

7x - 6 ( x - 19 ) = 12x - 21

7x - 6x + 114 = 12x - 21

7x - 6x - 12x = - 21 - 114

7x - 18x = - 135

- 11x = - 135

x = - 135 / - 11

x = 12, 27
