7th grade two-step equations and inequalities
Quick answer
This 7th grade (ages 12–13) playlist covers solving two-step equations, then writing, solving and graphing two-step inequalities, including when to flip the inequality sign. It starts with Math Antics' "Solving 2-Step Equations" and continues with Math with Mr. J and Khan Academy. Loop one example with A–B and repeat it at 0.75×.

What should a student be able to do after this unit?
Solve equations such as 3x + 5 = 20, including ones with negatives, fractions and decimals; write an equation from a word problem; solve two-step inequalities; flip the sign when multiplying or dividing by a negative; and graph the solution on a number line.
How do saved sections help with a long practice video?
Mr. J's "Lesson + Practice" videos hold several problems. Save each problem as an A–B section on keys 1–9, so a student can try it on paper, then jump to that answer. Stop after N loops keeps sessions short.
Frequently asked questions
Why do you flip the inequality sign?
Multiplying or dividing both sides by a negative number reverses the order of the numbers, so the symbol must flip to stay true. Math with Mr. J's "Why Do We Flip the Inequality Sign" explains this with simple examples.
Is this a 7th grade topic everywhere?
Grade levels vary by country and school. In the US, two-step equations and inequalities usually come in 7th grade (ages 12–13), after one-step equations in 6th grade. Some students meet them earlier or later.
