lynn is 6 years older than Linda.The sum of their ages is 36. What is Linda's age.

Let x = Linda's age
x + x + 6 = 36
2x = 30
x = 15

This is pretty simple.
Let Linda's age be x.
So we have:
x + (x+6) = 36
2x + 6 = 36
2x = 36  6
2x = 30
x = 30/2
x = 15
Double checking, if Linda is 15, Lynn will be 21.
15 + 21 = 36
So x is definitely 15.
