T= trumpets
S= saxophones
T= s-10
S= 3t
Solve for t first in first equation by substituting the second equation into the first equation like this .
T=3t-10
T-3t=10
-2t=10
T=10/-2
T=5
Now substitute your t answer to second equation to find s .
S=3(5)
S=15
So you have 5 trumpets and 15 saxophones .
I hope this helps
