Front

(18 ÷ 2) × 3 – 17 = ?

Back

10 - First, divide 18 by 2 to get 9, then multiply by 3 to get 27, and finally subtract 17.

Front

Simplify: 12 - 6z - 5 + 10z

Back

7 + 4z - Combine like terms: -6z + 10z = 4z and 12 - 5 = 7.

Front

What is the first step to solve the equation: 3x = 44?

Back

Divide 3 on both sides - To isolate x, divide both sides by 3.

Front

Solve the equation: 7x - 9 = 33

Back

x = 6 - Add 9 to both sides to get 7x = 42, then divide by 7.

Front

Front

What is the solution to the equation: 2x + 3 = 11?

Back

x = 4 - Subtract 3 from both sides and then divide by 2.
