3) Solve.
1+(2x)/(x+4)=(3)/(x-1)
Not sure how to do this, any help would be appreciated, thank you!
do it as you do with all fractions. Multiply by the LCD. For example, to evaluate
2/3 + 4/7
you multiply by 21. So, here you have
1+(2x)/(x+4)=(3)/(x-1)
(1)(x+4)(x-1) + (2x)(x-1) = (3)(x+4)
x^2+3x-4 + 2x^2-2x = 3x+12
3x^2 - 2x - 16 = 0
I expect you can solve that one, right?
