Answer 1

$\frac{a + b}{2x} + \frac{a - b}{2x} = \frac{a}{x}$

$\frac{9 + 7y}{a + b} - \frac{5y + 5}{a + b} = \frac{4 + 2y}{a + b}$

$\frac{2c}{c - x} - \frac{c}{c - x} - \frac{x}{c - x} = 1$

$\frac{a + b}{2x} + \frac{a - b}{ - 2x} = \frac{b}{x}$

$\frac{2x}{5b} - \frac{1 - x}{ - 5b} = \frac{x + 1}{5b}$

$\frac{5a}{x - y} - \frac{7a}{y - x} = \frac{12a}{x - y}$

$\frac{3x}{a - 2b} + \frac{3y}{2b - a} = \frac{3x - 3y}{a - 2b}$

$\frac{2a - b}{a - b} - \frac{b}{b - a} = \frac{2a}{a - b}$

$\frac{a}{xy} + \frac{b}{yz} = \frac{az + bx}{xyz}$

$\frac{2x}{ab} - \frac{3x}{4ab} = \frac{5x}{4ab}$
