Final answer:
To solve the given system of equations, we need to find the values of x and y that satisfy both equations for each pair. We can do this by setting the expressions for y equal to each other and solving for x.
Step-by-step explanation:
To solve the system of equations, we need to find the values of x and y that satisfy both equations for each pair. Let's solve the given systems of equations one by one:
- y = x² + 4x + 7 and y = 2: Substitute 2 for y in the first equation and solve for x.
- y = x² - 2 and y = x + 5: Set the expressions for y equal to each other and solve for x.
- y = -x² - 3 and y = 9 + 2x: Set the expressions for y equal to each other and solve for x.
- y = -3x - 6 and y = 2x² - 7x: Set the expressions for y equal to each other and solve for x.
- y = x² and y = 10 - 8x: Substitute x² for y in the second equation and solve for x.
