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

• math -

Let x = Linda's age

x + x + 6 = 36
2x = 30
x = 15

• math -

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.
