Systems Of Linear Equations In Two Variables
Akopọ
One equation with two unknowns has endless solutions; pair it with a second equation and the answer usually pins down to a single point. Solving a system of two linear equations means finding the one pair of values that satisfies both at once, the exact spot where two lines cross.
In this lesson you will solve systems of two linear equations in two variables using elimination and substitution, the two reliable algebraic methods. You will learn to choose the easier route for each problem and to check your answer in both original equations.
