KS.8.EE. Expressions and Equations
Analyze and solve linear equations and inequalities.
8.EE.7. Fluently (efficiently, accurately, and flexibly) solve one-step, two-step, and multi-step linear equations and inequalities in one variable, including situations with the same variable appearing on both sides of the equal sign.
8.EE.7a. Give examples of linear equations in one variable with one solution (ݑ = Űݑ), infinitely many solutions (ΰݑ = ΰݑ), or no solutions (ΰݑ = ΰݑ). Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form ϰݑ = Űݑ, a = ΰݑ, or ΰݑ = ΰݑ results (where a and b are different numbers).
8.EE.7b. Solve linear equations and inequalities with rational number coefficients, including equations/inequalities whose solutions require expanding and/or factoring expressions using the distributive property and collecting like terms.
