Question

-1/4 (x-2)=2x-1/3
Me ajudem por por favor

Answer 1

Vamos lá:

$- \frac{1}{4}.(x - 2) = 2x - \frac{1}{3} \\\ - \frac{x}{4} + \frac{2}{4} = 2x - \frac{1}{3} \\\ - \frac{x}{4} - 2x = - \frac{1}{3} - \frac{1}{2} \\\ \frac{x}{4} + 2x = \frac{5}{6} \\\ \frac{9x}{4} = \frac{5}{6} \\\ 9x.6 = 4.5 \\\ 54x = 20 \\\ x = \frac{20}{54} \\\ x = \frac{10}{27}$

Espero ter ajudado.

Answer 2

Boa tarde.

veja:

$\frac{-1}{4}.(x - 2) = 2x - \frac{1}{3}$

- x / 4 + 1 / 2 = 2x - 1 / 3 

mmc = 12

- 3x + 6 = 24x - 4 

6 + 4 = 24x + 3x

10 = 27x

x = 10 / 27
