# Use the elimination method please?/ Thanks!

##### 1 Answer

It’s too late for this answer now (sorry) but I can explain the elimination method if that helps ...

#### Explanation:

In essence you are trying to get the equations so that they contain a factor (or variable) that can be removed, leaving a simple linear equation (such as 5a = 2 or whatever.)

Off we go ...

First number the equations for reference:

(I) x 6 gives

(II) x 8 gives

(III) - (IV) leaves **y has been “eliminated”**

Substitute (V) into (I) to give:

So multiplying (VI) by 6 gives:

You should always check you have got it right (I mess up continuously) by resubstituting both values you have got into one of the *original* equations so choosing (I) it becomes:
