Note that if we add each side of the 2 equations, y will cancel out:
-12x-y+(17x+y)=6+4
5x=10
x=2
Substituting x=2 in either of the equations, we find the value of y.
Let's use the first equation:
-12x-y=6
-24-y=6
-y=24+6
-y=30, so y=-30.
Thus, the solution is (2, -30)
Answer: C
10 students (brass)=40% of band
4 students (strings)=16% of band
? students (other)=44% rest of band

(cross multiply to find ?){don't forget to turn percents into decimals}
?=11
There are 25 students in total in the band.

The mistake was that 
not 
Using the fact that the right answer would be
.
z and 100 are on the same line so the total is 180
180-100=z
80=z
