y=x-21
y= 1/4 x
1/4 x = x-21
x = 4x - 84
84 = 3x
28 = x
auditorium is 28 years old
gym is 7 years old

Okay, you have the gym: G
and the Auditorium: A
G + 21= A , becuase it's the gym's current age plus 21 years equals the auditorium's age.
Then, you have G= 1/4A (or 4G=A), because the gym is only 1/4 as old as the auditorium. Hope this helps.

G = A - 21
G = 1/4 A
A - 21 = 1/4 A
A- 1/4A = 21
3/4A = 21
A = 21*4/3
A = 7*4 = 28
auditorium = 28
G = 28 - 21 = 7
tada!!

You can't even spell, let alone use correct grammar... good luck! Is your internet connection stolen somehow?
