(5x – 3.6) – (4x + 1.2)

= 5x - 3.6 - 4x - 1.2

= 5x - 4x - 3.6 - 1.2

= x - 4.8

(6x^2 - 25x - 10) / (3x + 2)
= (6x^2/3x+2) - (25x/3x+2) - (10/3x+2)
= 2x - 29/3 R. 28/3

Simplify: 2x^2y + 7z^2y - xy + 4x^2y + 4z^2y - xy
Combine like terms:
x^2y: 2 + 4 = 6 6x^2y
z^2y: 7 + 4 = 11 11z^2y
xy: -1 - 1 = -2 -2xy
Simplified expression: 6x^2y + 11z^2y - 2xy
Answer: 6x^2y + 11z^2y - 2xy
