The answer is B 2,142.72 because when you add it all up then multiply by 12 it will equal that.
-7 to make 4 so -4x=4 x=-1
The answer is x=-1
Hope this helps:)
Think of 6y as
y + y + y + y + y + y
Now subtract a y from that.
y + y + y + y + y + y - y = y + y + y + y + y = 5y
change the 6 ito - 6 by turning to left side then you will have -3 -6 now you can add them (- + -) is + so you can add them the sign of 6 is greater so the answer is -9
