Step-by-step explanation:
Hey there!☺
In our first step, we will simplify both sides of the equation:
Now subtract 4 from both sides:

Part A Answer: Company A: (Wx6)+12 Company B: (Wx5)+15
The varible used was W because windows start with a W i chose this as the variable because it is for the certain NUMBER of windows.
Part B:Company A: 8x6=48+12=$70 for 8 windows and service charges.
Company B:8x5=40+15=$55 for 8 windows and service charges.
Company B would charge less for 8 windows.
Part C:My work for Company A: 6x6=36+12=$48 for 6 windows and service charges
My work for Company B: 6x5=30+15=$45 for 6 windows + service charges
$48-$45=$3
Answer for Part C: $3 would be saved by using the services of Company B instead if Company A to clean 6 windows.
X = 40, Y = 15
40(2) + 15(2) = 80 + 30 = 110 :)
