Question

Use the substitution method to find the solution(s) to the system of equations. Show all work for full credit.
y = x2
y = x + 2

Answer 1

\[
\begin{align}
y&=x^2\\
y&=x+2
\end{align}
\]
Where are you stuck..?

Answer 2

I'm not sure how to solve it. I keep getting no solution.

Answer 3

you need to make a substitution so that you are relating the x variables to eachother.

Answer 4

Put \(x^2\) where \(y\) is in \(y=x+2.\)

Answer 5

Solve that equation. Then find \(y\).

Answer 6

Y=X2

X2=X+2

X2-X-2=0

(X+1)(X-2)=0

Continue from there
Find X & replace on the equation to find Y

Simple

Answer 7

you could also graph both equations and look for the point of intersection.
