Answer 3

This looks like a combination of coefficients and variables. Let's simplify it step by step.

(1,3Х - 4,5У) - (0,5У - 4,2Х)

Distribute the minus sign through the second parenthesis:

1,3Х - 4,5У - 0,5У + 4,2Х

Combine like terms:

(1,3Х + 4,2Х) - 4,5У - 0,5У

Combine the X terms:

5,5Х - 4,5У - 0,5У

So, (1,3Х - 4,5У) - (0,5У - 4,2Х) simplifies to 5,5Х - 5У.
