Question

A)x+ax/x+bx
b)10x/7a +3x/7a
c)10/x - 25/3x
d)3/a - 5y/y
e)7a/m² - 2a/5m
f)3x/2 : 6x²/4
e)2y/x : 10x/3xy

Answer 1

     $\frac{x+ax}{x+bx} = \frac{x(1+a)}{x(1+b)} = \frac{1+a}{1+b} \\ \\ \frac{10x}{7a} + \frac{3x}{7a} = \frac{10x+3x}{7a} = \frac{13x}{7a} \\ \\ \frac{10}{x} - \frac{25}{3x} = \frac{3.10-25}{3x} = \frac{30-25}{3x} = \frac{5}{3x} \\ \\ n$
