Answer:

Y=6000

Step-by-step explanation:

  • The equation is (y=1680+0.72y) you can also have the equation as (1y=1680+0.72y)
  • Since you want to isolate the variable (y) you do the opposite of what is expressed, and whatever you do to one side you also do to the other side
  • (1y=1680+0.72y) First, you would subtract 0.72y from both sides. You would end up with: (0.28Y=1680)
  • You then would have to divide each side by 0.28 because originally you are multiplying by 0.28.
  • The result would then be Y=6000
