Answer 1

To find XY, substitute the given values in the equation XY = 4Y-1. To find Y, substitute XF and YF in the equation XF = 9Y-23. To find YF, substitute XF and XY in the equation YF = 2C+10. To find XF, substitute XY and YF in the equation XF = 9X-15.

Step-by-step explanation:

To find XY, we use the given equation XY = 4Y-1. Substituting YF = 8 into the equation, we have XY = 4(8)-1 = 31.

To find the value of Y, we substitute XF = 9Y-23 and YF = 8 into the equation. This gives us 9Y-23 = 8. Solving for Y, we get Y = 3.

To find YF, we substitute XF = 85 and XY = 5c-9 into the equation. This gives us 85 = 5c-9. Solving for c, we get c = 18. Substituting c = 18 into the equation YF = 2C+10, we get YF = 2(18)+10 = 46.

To find XF, we substitute XY = 4X+10 and YF = 2X-1 into the equation. This gives us 4X+10 = 2X-1. Solving for X, we get X = 3. Substituting X = 3 into the equation XF = 9X-15, we get XF = 9(3)-15 = 12.
