: Solving for x and y. I know its basic but i can't find any examples to go to school off of.
there are many ways to solve these types of problems. one is to notice that both equations are written as y=something. so the somethings must equal.
that is; if y=x2+3x-5, and y=4x+1,
this gives you a quadratic equation in one variable. you can solve it for x. then you can use one of the original equations to figure out y.
(don't be surprised when you get two solutions!)
