The first step is to multiply both side by 8, as this will cancel out the 8 that is beneath the 6-2x. This will then make the equation look like this: 8y = 6-2x. As we are making X the su...

To solve simultaneous equations we want to use only one variable so either x or y. Therefore we need to eliminate (get rid of) one of the variables .If you multiply x - 3y = 9 by 5 you will get 5x - 15y =...

You have to look at the where the angle is located and what sides of the triangle relative to the angle you are given. The hypotenuse is always the longest line of the triangle, the opposite is always the...

To solve the equations the first step to take is to eliminate one of the variables x or y so we can get the value of it and then substitute it back in to get the value of the other.
One way to do thi...
