8th Grade Common Core: 8.EE.8b

Common Core Identifier: 8.EE.8b / Grade: 8

Curriculum: Expressions And Equations: Analyze And Solve Linear Equations And Pairs Of Simultaneous Linear Equations.

Detail: 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.
