Answer 1

$Hey \: mate, \: here \: is \: your \: answer...$
________________________________

$\frac{5x}{4} + \frac{6 - x}{8} = \frac{6(x + 3)}{3} - \frac{1}{6} \\ \\ \frac{10x + 6 - x}{8} = \frac{12(x + 3) - 1}{6} \\ \\ \frac{9x + 6}{8} = \frac{12x + 36 - 1}{6} \\ \\ 6(9x + 6) = 8(12x +35) \\ 54x + 36 = 96x + 280 \\ 54x - 96x = 280 - 36 \\ - 42x = 244 \\ x = \frac{244}{ - 21} \\ \\ x = - \frac{122}{21}$
