B=age of Beth,

J=age of Julio

G=age of Gerald

D=age of Debra

Equations, expressed in terms of J

B=J+2

G=2B=2(J+2)=2J+4

D=2G=2(2J+4)=4J+8

Finally

J+B+G+D=38 and substitute above values:

J+(J+2)+(2J+4)+4J+8=38

8J+14=38

J=3

Backsubstitute J in the above equations to get the ages of Beth, Gerald and Debra.
