11Convert your percentage into a decimal:
Multiply your decimal by 55:
Since 30 lights are 40% of them:

Answer:
(-5, -8)
Step-by-step explanation:
-3x+3y=-9
-3x+y=7
----------------
simplify -3x+3y=-9 into x-y=3
----------------------------------------
y=x-3
-3x+y=7
------------
-3x+(x-3)=7
-3x+x-3=7
-2x-3=7
-2x=7+3
-2x=10
x=10/-2=-5
y=-5-3=-8
x=-5, y=-8
