Front

How do you solve the equation x + 5 = 12?

Back

Subtract 5 from both sides: x = 12 - 5, so x = 7.

Front

How do you solve the inequality 3x < 12?

Back

Divide both sides by 3: x < 4.

Front

What is the solution to the equation 4 + x = 12?

Back

x = 12 - 4, so x = 8.

Front

What is the solution to the equation 2x = 20?

Back

Divide both sides by 2: x = 20 / 2, so x = 10.

Front

What is the solution to the inequality s + 9 ≥ -25?

Back

Subtract 9 from both sides: s ≥ -25 - 9, so s ≥ -34.

Front

What is the solution to the equation 5x = 45?

Back

Divide both sides by 5: x = 45 / 5, so x = 9.
