In that case, 1/2 of X = 4, making Y= 8

From there, we can simply state y=2x

des:

y=1/2x+4 solve for y in terms of x

y = 1/2 * x + 4

now the idea is to get the x on one side by itself. So you need to keep thinking, what can I get rid of and how do I do that.

What is the opposite of adding 4 ? Well taking it away of course. But you have to do it to both sides.

y-4 = 1/2 * x +4-4

y-4 = 1/2 * x

Now what is the opposite of halving something. How about timesing it by 2.

2(y-4) = 2 * 1/2 * x Don't forget the brackets

x=2(y-4)
