The number you thought of was 5
Step-by-step explanation:
You thought of a number
- Doubled it
- Then added 3
- The result multiplied 4
- The answer was 52
Assume that the number was x
∵ The number = x
∵ The number was doubled
- Double means multiply it by 2
∴ The result = 2x
∵ You added 3
∴ The sum = 2x + 3
∵ You multiplied the sum by 4
∴ The product = 4(2x + 3)
∵ It came 52
∴ 4(2x + 3) = 52
- Simplify it
∴ 4(2x) + 4(3) = 52
∴ 8x + 12 = 52
- Subtract 12 from both sides
∴ 8x = 40
- Divide both sides by 8
∴ x = 5
