The disappearing number

When a number is doubled and then 7 is subtracted, the result is the same as when the number is tripled and then 17 is subtracted.
What is the number?

  1. Let the number of sweets Sophie started with be x.

    Gave half to Lucy:
    Left with:
    x ÷ 2

    Gave a third of what's left to her brother:
    A third of x ÷ 2 is x ÷ 6
    After giving that away:
    Remaining = x ÷ 2 - x ÷ 6

    To subtract these, use a common denominator (6):
    (3x - x) ÷ 6 = 2x ÷ 6 = x ÷ 3

    Then she ate 6 sweets:
    Remaining = x ÷ 3 - 6

    This equals 10 sweets (what she has now):
    x ÷ 3 - 6 = 10

    Solve for x:
    Add 6 to both sides:
    x ÷ 3 = 16
    Multiply both sides by 3:
    x = 48
