Answer:
The answer should be a positive 3 instead of a negative.
Step-by-step explanation:
The error is in the first step. The equation should've been set up like this...
-14+2y+4=4
-10y+2y=-4
2y=-4+10
2y=6
y=3
(probably) 96
2 buildings, 3 floors, 16 windows.
first, 16x3=48
and then 48x2=96
So, the total number is 96.
18x+27y
33?
15 :)ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ
