    Ty is x years old now and Paul is 12 years older than Ty. 

    In two years Paul will be exactly twice as old as Ty is then.

    P = Ty + 12 = x + 12

    2(x + 2) = P + 2

    2(x + 2) = x + 14

    x = 10

    Ty is now 10 years old.

    Ty is x years old now and Paul is 12 years older than Ty

    Ty = x

    Paul = x + 12

     

    In two years Paul will be exactly twice as old as Ty is then

    (x + 12) + 2 = 2(x + 2)

    Restate

    x + 14 = 2x + 4

    Subtract 4 from both sides

    x + 10 = 2x

    Subtract x from both sides

    10 = x

    x = 10

    Ty is 10 years old today <––––––––

  • Ty = x

    Paul = x + 12

    (x + 12) + 2 = 2x

    x + 14 = 2x

    14 = x

    Ty is 14 years of age
