Solving one step inequalities

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using symbols such as <, >, ≤, or ≥.

Front

What does the symbol '≥' mean?

Back

'≥' means 'greater than or equal to'.

Front

What does the symbol '≤' mean?

Back

'≤' means 'less than or equal to'.

How do you solve the inequality y + 5 ≥ 2?

Back

Subtract 5 from both sides: y ≥ 2 - 5, so y ≥ -3.

Front

What is the solution to the inequality 30 + n ≥ 50?

Back

Subtract 30 from both sides: n ≥ 50 - 30, so n ≥ 20.

How do you solve the inequality -9h > -63?

Back

Divide both sides by -9 (remember to flip the inequality): h < 7.

Front

What is the solution to the inequality x - 2 < 5?

Back

Add 2 to both sides: x < 5 + 2, so x < 7.

Front

How do you solve the inequality x + 5 ≤ 13?

Back

Subtract 5 from both sides: x ≤ 13 - 5, so x ≤ 8.

Front

What is the first step in solving an inequality?

Back

Identify the inequality symbol and isolate the variable on one side.

Front

What happens to the inequality sign when you multiply or divide by a negative number?

Back

The inequality sign flips direction.
