Answer:
Judy is 16 years old
Stepbystep explanation:
J = Judy's age
A = Adams age
J = 2A
Six years ago (subtract 6 from the ages)
(J6) = 5*(A6)
Distribute
J6 = 5A  30
Substitute J = 2A
2A 6 = 5A 30
Subtract 2A from both sides
2A2A 6 = 5A2A 30
6 = 3A 30
Add 30 to each side
6+30 = 3A30+30
24 = 3A
Divide by 3
24/3 = 3A/3
8 = A
Adam is 8 years old now
We need to find Judy's age
J = 2A
J = 2*8
J = 16
Judy is 16 years old
