# Simple maths problem and i'm having a bad night! watch

1. arghhh i hate it when i can't do algebra when i know i should be able to....

The answer i've checked in x=1 but i have nooo idea how to get there and keep coming out with quadratics etc. All help appreciated...

4/x - 3 = 4/x+3

2. If you're coming out with quadratics, can you not use the quadratic equation to solve them?
3. if you times it all through by x(x+3) then you get a very factorisable quadratic- are you sure you've added everything up right?
4. yeah just having a VERY VERY bad night.
5. bring the two fractions on one side. 4/x -4/x+3 = 3
then times out to get equal denominator which will be (4(x+3) - 4x)/x(x+3) = 3
the times the denomonator by 3 to get. (4(x+3) - 4x) = 3x(x+3)
then rearrange and form a quadratic of the form (3x +12)(x-1) then x=1 or x= -12/3 , and your answer is one because either it will say x is positive integer or it is the only x value to satisfy that equation. btw which level is this question, gcses or a level ? thanks i hope that helps
6. if I've understood your question correctly:

multiply by !!! here you have to input the condition
and you get:

QED
