Problem 26 of 7
Solve the standard-form linear-quadratic system by elimination or rearranging: y=x+3, y=x^2+x-1.
Using a hint is okay. It just tells the trainer to give you a little more review.

Walkthrough
Full solution stays hidden until you ask for it.
1. Rewrite equations so the same variable can be eliminated or substituted.
2. Form and solve the quadratic in one variable.
3. Use the linear equation to recover the paired coordinate.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Points that solve only the rearranged quadratic but fail the original system.
