You can put this solution on YOUR website! Ok well first you need to expression the equation in terms of y. We know that x is equal to 4 times y. So we can replace x with 4 times y as below:
We can then take y away from 4y to give
So we know that 3 times y is equal to 60. So y must be 20. We can find this by dividing both sides by 3 to give
So now we know y. In order to find x we can use the value for y in the original equation
So we know a number take away 20 equals 60 so x must be 80. Or another way is to to add 20 to both sides to give
Does this make any sense? Any questions?
