1. Solve for x: 3x + 7 = 22
2. Solve for y: 5y - 12 = 18
3. Solve for z: (z / 4) + 5 = 9
4. To solve 2x + 10 = 20, the first step is to 10 from both sides.
5. In the equation (a / 3) - 4 = 6, the second step is to both sides by 3.
6. Which operation would you perform first to solve 4(x - 5) = 28?
Add 5 to both sides
Subtract 5 from both sides
Divide both sides by 4
Multiply both sides by 4
7. To solve -2x + 8 = 16, the first step is to add 8 to both sides.
True
False
8. A number is multiplied by 5, then 10 is subtracted from the result. If the final answer is 35, what is the number? Write and solve a three-step equation.
