We need to solve this so we have a positive x term on one side.

First we can subtract 3 from both sides of the inequality to get:

5x<3x-9

Next we can subtra...

We need to factorise this equation to solve it.

The first step for factorisation is to make the equation equal to zero. We can do this by subtracting x from both sides to get:

...

The first step to eliminate one of the unknowns, in this case x or y. This can be done by making the coefficient (the number before) of one of the unkowns the same number...

x³-x=x(x²-1)=x(x+1)(x-1)

Equation 1: 2x + y = 14 Equation 2:   4x - y = 10

Add the two equations together to get 6x = 24. Therefore x = 4.

Then substitute the value x = 4 into equation 1 and solve. ...
