Your numbers are 10 and -4.

-2x -4y= -4
2x + y = 16
0x - 3y = 12
-3y = 12
y = -4

x+ 2y = 2
x + 2 ( -4) = 2
x- 8= 2
x= 10

What number is 15% of 80?<br> use percent proportions
vova2212 [387]
!5% is equivalent to 15 parts over the whole 100 part. It is written in proportions as 15/100. 

Similarly, you need to find how many parts in 80 are equivalent to 15%or 15/100. So, just equate both equation with x as an unknown.

x/80 = 15/100
x = (15/100)*80
x = 12

Thus, the 15% of 80 is 12.
