Question

what are the solutions to the following system of equations?
y = x2 + 3x - 7
3x - y = -2

Answer 1

Put the value of y in the second equation.

Answer 2

From equation 1 : \( y = x^2 + 3x - 7 \)

Now, put this value of y at the place of y in the second equation.

\(3x - y = -2 \\
3x - (x^2 + 3x - 7 ) = -2 \)

Now, you can simplify this and obtain and equaton in single variable. Solve for x and then plug-in the value of x in the equation 1. Solve for y then!
