Let beth's age be x, and john's age be y.
then from the first sentence, we derive that beth is 16 yrs younger than john
x + 16 =y
from second sentence, we have that
y+10=2x
then we get the following equations
x+16=y  ..........(eqn 1)
y+10=2x   ........(eqn 2)
substituting y+x+16 from eqn 1 into equation 2, gives
x+16+10=2x
which gives x=26
then y=x +16...
y=26+16
y=42
beth is 26 years and john is 42 years
