Mississippi Math FA.A.7
The Standard
Fluently solve and check multi-step equations and inequalities with an emphasis on the distributive property, variables on both sides, and rational coefficients. Explain each step when solving a multi-step equation and inequality. Justify each step using the properties of real numbers.

What This Standard Means
What Students Need to Do
- Students solve equations and inequalities with parentheses, fractions, and a variable on each side. They explain why each move is valid and check their answers.
What Mastery Looks Like
- A student distributes correctly, clears fractions on both sides, and isolates the variable. They name the property behind each move and reverse an inequality when dividing by a negative. They substitute to check an equation and test values on either side of an inequality boundary.
Common Misconceptions
- Some students multiply only the first term inside parentheses or clear fractions on only one side. Others move a term across the equal sign without changing its sign. They may forget to reverse an inequality when dividing by a negative.
How to Assess It
- Exit ticket: Solve −(1/2)(x − 2) > x + 4. Label the property used at each step, then test x = −4 and x = 0.

Ways to Teach It
Use a balance mat, paper x-cards, and half-unit squares to model 2(x + 1/2) = x + 4.
Ask students to explain in writing why 3(x − 2) = x + 4 becomes 3x − 6 = x + 4.
Give pairs step cards for −2(x − 1) > x + 5; have them order the steps and mark where the inequality flips.
Compare phone plans costing $12 plus $0.08 per text and $18 plus $0.05 per text; find when the first costs less.
