Question 412479: I am not sure if this is the correct category and I apologize if it is.
Question:
Solve algebraically these simultaneous equations.
x^2 + y^2 = 17
y = x + 3
I have rearranged to make; x^2 + x^2 + 6x - 8
but how do I remove one of the x^2's so I can put the equation into brackets and solve?

I corrected your category selection. Systems of Equations that are Not Linear.

Why would you want to remove one of the terms? There are two of them, so add them together:



Multiply by



Which is a factorable quadratic equation.
