Answer 1

$e) \: \frac{5}{12} + \frac{x}{6} = \frac{x}{4} + \frac{1}{3} \iff \: nc = 12 \\ 5 + 2x = 3x + 4 \\ \implies 3x-2x = 5-4 \implies \: x = 1 \\ \\ \\ f) \: \: \frac{x - 1}{5} + \frac{x - 2}{3} = 2 - \frac{x - 2}{15} \\ \iff \: nc = 15 \\ \small\implies 3(x - 1) + 5(x - 2) = 15 \times 2 - (x - 2) \\ \implies 3x - 3 + 5x - 10 = 30 - x + 2 \\ \implies 8x + x = 32 +1 3 \\ \implies 9x = 45 \\ \implies \: x = 5$
