Question

anonymous · Answer

25 smaller 87 larger?

myininaya · Answer

$$x+y=112$$
from first sentence
-----------------
Assume x is the smallest!
$$y-3x=12$$
from second sentence

myininaya · Answer

$$y=3x+12 \text{ from second equation}$$
now plug this into the first equation and solve for x

myininaya · Answer

$$x+(3x+12)=112$$
$$4x+12=112$$
$$4x=100$$
x=25
then 
y=3(25)+12=75+12=87
so yes
