Find a,b: $\rm \frac{a}{x+2} + \frac{b}{x} = \frac{8x + 10}{x(x+2)}$

Find a,b: $\rm \frac{a}{x-5} - \frac{b}{x+3} = \frac{4(x+9)}{(x-5)(x+3)}$

Find a,b: $\rm \frac{a}{2x-3} - \frac{b}{3x + 4} = \frac{x + 7}{6x^2 -x-12}$

Find b: $\rm \frac{b}{x^2 - 5x} - \frac{x}{5x - 25} = - \frac{x + 5}{5x}$

Find b: $\rm \frac{b}{x-2} + \frac{x+3}{2-x} = \frac{1-x}{x-2}$

Find a: $\rm \frac{1}{(x-y)(x-z)} - \frac{a}{(z-x)(y-z)} = \frac{1}{(x-y)(y-z)}$

Find a: $\rm \frac{a}{xy - y^2} + \frac{y}{xy - x^2} = \frac{x + y}{xy}$
