Question

How do I solve this for x?? 3/(1-3x) + 5/(2-x) + (9-2x)/(3x^2 - 7x + 2) = 0

Answer 1

First step is to find a common denominator (LCD, or least common denominator). Then multiply every term by the LCD.

Answer 2

as (1-3x)*(2-x)=3x^2-7x+2 , you should multiple 3x^2-7x+2 to each side then:
3*(2-x)+5*(1-3x)+9-2x=0 and then x=1.
