Let the numbers be x and y

x + y = 33
-
x + 4y = 108
__________
3y = 75
__________

3y = 75

y = 75/3

y = 25

x + y = 33
x + 25 = 33
x = 33 - 25 =8

The numbers are 8 and 25.

okay you have 2 sum unknow lets call them X+Y

so X+Y=33, 4X=108

Get X by it self then plug it in 4X=108

X=-Y+33
4(-y+33)= 108
-4y+132=108 Then subtract the 132
-4y=-24 Y=6 then to find X subtract 33-6=27
Y=6 X=27 if you check it works out
