Answer 1

e) Tira o MMC de 2,3 e 4, que e 12
$\frac{6x+8x-9x}{12} = 1$
6x + 8x - 9x = 12
14x - 9x = 12
5x = 12
x = $\frac{5}{12}$
f) x - x - 3x = $- \frac{1}{2} + \frac{3}{4} - 5$
-3x = $\frac{(2+3-20)}{4}$
-3x = $-\frac{15}{4}$
x = $\frac{15}{4} :3$
x = $\frac{15}{4} . \frac{1}{3}$
x = $\frac{15}{12}$
