Answer 1

$a) \: \frac{x}{2} - \frac{x}{ 4} = \frac{1}{2} \\ \frac{1}{4} x = \frac{1}{2} \\ \frac{1}{4}x = 2 \\ 4 \times \frac{1}{4} x = 4 \times 2 \\ x = \pink{8}$

$b) \: \frac{x}{2} - \frac{x}{4} = 5 \\ \frac{1}{4}x = 5 \\ x = \pink{20}$

$c) \: \frac{x}{2} + 4 = \frac{1}{3} \\ 3x + 24 = 2 \\ 3x = 2 - 24 \\ 3x = - 22 \\ x = \pink{- \frac{22}{3}}$
