Demetrius is 4 years older than Taylor. In 4 years the sum of their ages will be 64. How old is Demetrius now?

Answer 1

FIrst, you'll need to create some equations.

1. Since Demetrius is 4 years older than Taylor, let d = t + 4.
2. Since the sum of their ages 4 years from now will be 64, let (d + 4) + (t + 4) = 64.

Next, plug the equation for d in #1 above into the equation in #2 and solve for t to find Taylor's age now.

1. ((t+4)+4) + (t+4) = 64

Then, plug that number into the equation from #1, d = t+4, and solve for d to find Demetrius's age now.

Answer 2

D=T+4

D+4 + T+4+ = 64

(T+4)+4+T+4=64

2T + 12 = 64

2T = 52

T = 26

Taylor is 26

Demetrius is 30.
