Hello, Spixol1231

Three years from now, Ann will one-third of her mother's age.
Eighteen years from now, Ann will be half her mother's age.
How old is her mother now?

Let = Ann's age now.
Let = Mom's age now.

Three years from now, they will both be 3 years older.
. . Ann will be years old.
. . Mom will be years old.

At that time, Ann's age is one-third Mom's age.
. .


Eighteen years from now, they will both be 18 years older.
. . Ann will be years old.
. . Mom will be years old.

At that time, Ann's age is one-half Mom's age.
. .

Now solve the system of equations.

Thanks heaps
