Question

How do I solve this system of equations?
y=x^2+3
y=x+5

Answer 1

you have both equations equalling y, so why not let both of them equal one another? try that and simplify

Answer 2

so to get you started, you should have something like this...
x^2 + 3 = x + 5
so x^2 - x - 2= 0

do you understand why?

Answer 3

Yep I got X=2 or -1 as my solutions

Answer 4

Really sorry for the super late response! anyway, yup thats correct! now that you have your have your x solutions out, substitute them into either equations to get out your y solutions, and there you have it. :)
