  5. Check your answer by substituting both values into either of the original equations.

How do you solve 3 simultaneous quadratic equations?

Pick any two pairs of equations from the system. Eliminate the same variable from each pair using the Addition/Subtraction method. Solve the system of the two new equations using the Addition/Subtraction method. Substitute the solution back into one of the original equations and solve for the third variable.
