Grade 8 - Expressions & Equations
Standard 8.EE.C.8b - Find the number of solutions to a system of equations.
Included Skills: Algebra
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.
