What are the solutions to the following system of equations?
y = x2 + 3x − 7
3x − y = −2

and

Step-by-step explanation:

we have

-----> equation A

------> equation B

we know that

The solution of the system of equations is equal to the intersection point both graphs

Using a graphing tool  

see the attached figure

There are two intersection points

Therefore

The system of equations has two solutions

The solutions of the system of equations are the points and

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

a
