Solving Simultaneous Linear Equations

This animated “Math Shorts” demonstrates how to solve two equations with two unknowns.

Common Core State Standards: CCSS.Math.Content.8.EE.C.8b (Grade 8): Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6.
