Question

caucule a equação

4 • (x - 1) -2 • (3x + 4) = 6​

Answer 1

Resposta:

$-9$

Explicação passo-a-passo:

$4.(x - 1) -2. (3x + 4) = 6\\4x-4-6x-8=6\\-2x-12=6\\2x=-12-6\\2x=-18\\x=\frac{-18}{2} \\x=-9$

Answer 2

4(x-1) - 2(3x+4) = 6

4x - 4 -6x -8 = 6

4x -6x -4 -8 =6

-2x - 12 = 6

-2x = 6 + 12

-2x = 18

x = 18/-2

x = -9
