The first thing to be aware of with grouped frequency is that we are not given the exact data, but instead we are told that we have some data and we have been able to divide it into set groups. Imagine we...

x < -3

y+y=2y
x×x=x²
therefore, y+y-x×x=2y-x²

In order to solve the question, we must find the value of y. First, we collect 'like terms'. This is when we put all the numbers on one side of the equals sign and put all the terms with y in it on the ot...
