Solving One-Step Adding/Subtracting Inequalities

Front

What is an inequality?

Back

An inequality is a mathematical statement that shows the relationship between two expressions that are not equal, using symbols like <, >, ≤, or ≥.

Front

How do you solve the inequality -4 + y < -8?

Back

Add 4 to both sides: y < -4.

Front

What does the symbol '≤' mean in an inequality?

Back

The symbol '≤' means 'less than or equal to'.

Front

How would you solve the inequality m - 9 ≤ 20?

Back

Add 9 to both sides: m ≤ 29.

Front

Is 3 a solution to the inequality x > 10?

Back

No, because 3 is not greater than 10.

Front

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

Back

Subtract 30 from both sides: n ≥ 20.

Front

What does the symbol '>' mean in an inequality?

Back

The symbol '>' means 'greater than'.

Front

How do you check if a number is a solution to an inequality?

Back

Substitute the number into the inequality and see if the statement is true.

Front

What is the solution to the inequality -2x < 6?

Back

Divide both sides by -2 (remember to flip the inequality): x > -3.

Front

What does the symbol '<' mean in an inequality?

Back

The symbol '<' means 'less than'.
