Answer:
15% of 20 is 3
Step-by-step explanation:
because 15/100 can be reduced if you divide by 5 which will be 3/20. After you multiply 3/20 by 20/1. So 20*3 is 60 divided by 20 because 20*1 equals 20 you get 3.

5(5x-3y=6)
3(2x+5y=-10)
25x-15y=30
6x+15y=-30
31x= 0
x = 0
5(0)-3y=6
-3y=6
y= -2
(0,-2)
