Sheri's
age=x
terry's
age=y
in
20 years
x+20
<span>=y
equation 1</span>
in 10
years
y+10<span>=2*x equation 2</span>
resolving
y=x+20 equation 1
y=2*x-10 equation 2
x+20 =2*x-10
2*x-x=20+10
x=30
y=x+20--------------y=30+20=50
Sheri's
age=x------------------30 years
terry's
age<span>=y-------------------50 years</span>
