Final answer:

To solve for X and Y in the equation 38.7 = 3X + 2.5Y, isolate one variable in terms of the other. X is equal to 12.9 minus two-thirds of Y, and Y is equal to 15.48 minus 1.2 times X.

Step-by-step explanation:

To solve for X and Y in the equation 38.7 = 3X + 2.5Y, we need to isolate one variable in terms of the other. Let's isolate X:

38.7 - 2.5Y = 3X

Divide both sides by 3

12.9 - (2/3)Y = X

So, X is equal to 12.9 minus two-thirds of Y. Now, let's solve for Y:

38.7 - 3X = 2.5Y

Divide both sides by 2.5

15.48 - 1.2X = Y

Therefore, X is equal to 12.9 minus two-thirds of Y, and Y is equal to 15.48 minus 1.2 times X.
