    I am stuck on the below question.

    Amy is x years old.
    Patel is 5 years older than Amy.
    Next year Patel will be twice as old as Amy.
    How old is Amy now.

    The answer is:
    2(x + 1) = x + 6
    2x + 2 = x +6
    x = 4

    I don't understand the answer.

    Is it....
    Amy would be x and Patel would be x + 5

    So after a year has passed you add one to the x and one to the 'x+5'. I'm still having trouble explaining the answer. Could someone help me out please?

    Thanks

    Amy is x years old. Patel is x+5 years old. Fast forward one year, we have Amy being x+1 years old, and Patel being x+6 years old.

    Patel is now twice as old as Amy, so 2*(Amy's age) = (Patel's age) hence 2(x+1) = x+6

    You was on the right track. Amy is x years old and Patel x + 5, that means she is five years older than Amy. Next year, both are a year older, so Amy has x + 1 and Patel x + 6 by adding (what you thought). Furthermore Patel is twice older in this coming year, so you multiply Amy's age by two, That leads to the equation above:

    2*(x + 1) = x + 6
