answer is (2,1)
y = 6x – 11
-2x – 3y = -7
Substitute 6x - 11 for y in the second equation
-2x – 3(6x-11) = -7
-2x – 18x +33 = -7
-20x + 33 = -7
Now subtract 33 on both sides
-20x = -7 - 33
-20x = -40 ( divide by -20 on both sides)
x= 2
We know y = 6x -11
Plug in 2 for x and find out y
y = 6(2) -11= 12 -11 = 1
So answer is (2,1)

Step-by-step explanation:
Answer:
Machine B
Step-by-step explanation:
Since, Machine A covers
square feet in
hours,
Rate at which the Machine A is covering = 
= 
= 2.5 square feet per hour
Machine B covers
square feet in
hours,
Rate at which the Machine B is covering = 
= 
= 
= 3.33 square feet per hour
Therefore, Rate of Machine B is greater.
