3. Solve to determine the unknown variable in the
equation.
What are the values of x?
Solve this system of equations:
y = x2-3x + 12
y = -2x + 14
1. Isolate one variable in the system of equations, if
needed
y = x2 – 3x + 12
y = -2x + 14
2.Use substitution to create a one-variable equation.
-2x + 14 = x2-3x + 12
O(-2, 1}
O {-2,4}
O {-1, 2}
O{-1,4}
