Question

-(3x+2y)-(5y-9x)-(2x-4y)

Answer 1

-(3x+2y)-(5y-9x)-(2x-4y)=-3x-2y-5y+9x-2x+4y=4x-3y

Answer 2

-(3х+2у)-(5у-9х)-(2х-4у)= -3х-2у-5у+9х-2х+4у=4х-3у

Answer 3

To simplify the given expression -(3x+2y)-(5y-9x)-(2x-4y), follow these steps:

Step 1: Distribute the negative sign through each expression inside the parentheses. Step 2: Combine like terms by collecting the variables with the same coefficients.

Let's go through the steps:

Step 1: -(3x+2y) becomes -3x - 2y -(5y-9x) becomes +9x - 5y (note the change of signs inside the parentheses when distributing the negative sign) -(2x-4y) becomes -2x + 4y

Step 2: Now, let's combine the like terms: -3x - 2y + 9x - 5y - 2x + 4y

Step 3: Combine the x and y terms separately: (-3x + 9x - 2x) + (-2y - 5y + 4y)

Step 4: Perform the additions: 4x - 3y

The simplified expression is 4x - 3y.
