Question

3x-2/4 - 4-x/2 = 2x - 7x-2/3​

(alguem me ajudar por favor)

Answer 1

$3x - \frac{2}{4} - 4 - \frac{x}{2} = 2x - 7x - \frac{2}{3} \\ 3x - 2x + 7x - \frac{x}{2} = - \frac{2}{3} + \frac{2}{4} + 4 \\ 8x - \frac{x}{2} = - \frac{2}{3} + \frac{2}{4} + 4$

Tirando o MMC dá 12, então

$\frac{96x - 6x = - 8 + 6 + 48}{12}$

Corta o 12

$96x - 6x = - 8 + 6 + 48 \\ 90x = 46 \\ x = \frac{46}{90} \\ x = \frac{23}{45}$
