Solve: 5x = 45
Answer: x = 9
Divide both sides by 5 to get x = 45 ÷ 5 = 9.
What is the next number in the sequence: 3, 6, 12, 24, ___?
Answer: 48
Each term is multiplied by 2, so 24 × 2 = 48.
If x/4 = 7, what is x?
Answer: 28
Multiply both sides by 4 to get x = 7 × 4 = 28.
A sergeant has y officers on duty. After 3 more officers join the shift, there are 15 on duty. What was y?
Answer: 12
The equation is y + 3 = 15, so y = 15 − 3 = 12.
What is the missing number in the sequence: 100, 91, 82, 73, ___?
Answer: 64
Each term decreases by 9, so 73 − 9 = 64.
Solve for x: 6x − 4 = 2x + 16
Answer: x = 5
Subtract 2x from both sides: 4x − 4 = 16; add 4: 4x = 20; divide by 4: x = 5.
If n + n + n = 39, what is n?
Answer: 13
