Hey guys, I came across this problem today that puzzled me.
y=-x +7
3/4x = 151/4 - 4y
So I'm supposed to use substitution right? But I have to isolate the 3/4, so how do I do that? I know this question is probably very easy, I just have no idea right now...I've been doing a lot of stuff such as volunteering etc, and i'm sleepy right now, probably as to why i can't think fully...thanks for any input on how to solve it using subsitution.
