Extend concepts of linear equations and inequalities in one variable to more complex multi-step equations and inequalities in real-world and mathematical situations. a. Solve linear equations and inequalities with rational number coefficients that include the use of the distributive property, combining like terms, and variables on both sides. b. Recognize the three types of solutions to linear equations: one solution (π₯ = π), infinitely many solutions (π = π ), or no solutions (π = π). c. Generate linear equations with the three types of solutions. d. Justify why linear equations have a specific type of solution.
