Question

6x -7(1-x)-(10x+4)=0

Answer 1

6x -7(1-x)-(10x+4)=0
6x - 7 + x - 10x - 4 = 0
7x - 10x = 11
-3x = 11
x = -11/3

Espero ter ajudado, bons estudos. Abraços

Answer 2

$6x - 7 (1 - x) - (10x + 4) = 0 \\ \\ 6x - 7 + 7x - 10x - 4 = 0 \\ \\ 6x + 7x - 10x = 4 + 7 \\ \\ 3x = 11 \\ \\ \\=> x = \dfrac{11}{3}$
