# Algebraic Fractions help

Why bother with a post grad course - waste of time? 17-10-2016
1. I usually know how to do them but now I've started to get a mental block.

What is an easy method to solve them? As well can people help solve these for me so that I get an idea for them myself, thanks.

1) (2x+3)/3 + 4x+1/2 = 43/2
2) (2x+3)/3 + (4x+1)/2 = 43/2x-1
3) (3x+2)/4x-2 + 2/3

3) (3x+2)/4x-2 + 2/3
get rid of fractions then rearrange and solve for x
3. Multiply both sides of the equation then expand and simplify and all should work out nicely.

So do I leave the = 43/2 untouched?

Well, there are multiple ways to do it. You'll end up multiply both sides of the equation by 6 anyhow, so it's not untouched per se.
7. what do you do when they are flipped around??
