Объяснение:

4x+4y-4t+5x-5t-4y=9x-9t= 4x+5x-9x=5t-9t+4t= -8t

Answer 2

It looks like you've provided a step-by-step simplification of the given equation. Let's go through the steps to see if the simplification is correct:

Original Equation: 4(x+y-t) + 5(x-t) - 4y = 9(x-t)

Step 1: Distribute the terms on the left side of the equation: 4x + 4y - 4t + 5x - 5t - 4y = 9x - 9t

Step 2: Combine like terms on both sides of the equation: (4x + 5x) + (4y - 4y) + (-4t - 5t) = 9x - 9t

Simplified: 9x - 9t = 9x - 9t

So, after simplification, the equation becomes 9x - 9t = 9x - 9t, which is true. It seems that your provided simplification steps are correct, and the equation holds true for any values of x, y, and t.
