Answer 1

What is the solution to the following system of equations?
y = x2 + 10x + 11
y = x2 + x − 7

(−2, −5)

(2, −5)

(−2, 5)

(2, 5)

Answer 2

Try Elimination method to solve these equations

Answer 3

You have 2 different expressions for y. So if both of those things are =y, then they are also equal one another.

So set the expressions =, then solve for x. The x^2 terms will conveniently go away, and you will have a simple linear equation in x to solve.

Once you have solved that, you will know the value of x. Then you can just substitute that value back into either of the equations to find y.
