7.7A Solving Two-Step Inequalities

​Solving Two-Step Inequalities

7th Grade: ​Lesson 7.7A

Match

Match each phrase with the correct symbol.

• $$>$$  

• $$\ge$$  

• $$\le$$  

• $$<$$  

• $$\ne$$  

greater than

greater than or equal to

less than or equal to

less than

not equal to

• greater than

• greater than or equal to

• less than or equal to

• less than

• not equal to

​When graphing inequalities, the arrow should point toward the possible solutions.

​Graphing Inequalities​

​x > 6 or 6 < x

means x is any number that is greater than 6.

> or <

≥ or ≤

Match

Match each statement with the correct graph.

y < 6

y > 6

y ≤ 6

y ≥ 6

• y < 6

• y > 6

• y ≤ 6

• y ≥ 6

​If you multiply or divide both sides by a negative number, you must flip the inequality symbol.

Solve like an equation by isolating the variable on one side of the inequality.
