the first time i worked this out i got x=1. which doesnt check out. so i know i need a common denominator which is 2(x-1) or is that where I am going wrong with this. THANKS
2/(x-1) + 1/x = 5/2
The common denominator is 2x(x-1). If you multiply both sides of the equation by 2x(x-1), you’ll get
4x + 2(x-1) = 5x(x-1)
Hope that helps.
11x-2=5x^2
but im stuck
The 5x^2 term tells you that this is a quadratic. What methods do you know for solving quadratics?
Start by getting all terms on one side of the equation and 0 on the other.
0 = 5x^2 –11x + 2
The quadratic formula will always work. Try that. You’ll get two answers; one is a whole number, and the other is a fraction.
