Problem 2 of 7
Solve the linear-quadratic system by substitution: y=x^2-4, y=2x-1.
Using a hint is okay. It just tells the trainer to give you a little more review.

Hidden until you reveal it.
System must contain one quadratic equation and one linear equation in x and y.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Set the two expressions for y equal to each other.
2. Solve the resulting quadratic equation for x.
3. Substitute each x-value into either original equation to find y.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
X-values alone without corresponding y-values.
