2. To solve for x in x - 7 = 3, you should 7 to both sides.
3. The operation inverse to multiplication is .
4. Solve for 'a': a + 8 = 15
5. What is the value of 'y' in the equation y + 12 = 20?
6. Solve for 'b': b - 6 = 10
7. Find 'z' if z - 4 = 11.
8. Which equation represents 'a number decreased by 9 is 15'?
9 - x = 15
x - 9 = 15
x + 9 = 15
9x = 15
