8.AT.B.3: Solve linear equations in one variable. a. Give examples of linear equations in one variable with one solution, infinitely many solutions, or no solution. Justify each example by showing how it can be rewritten in an equivalent equation in the form x=a, a=a, or a=b (where a and b are different rational numbers) and explaining what this form reveals about the solution. b. Solve linear equations in one variable with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and combing like terms.
