-(3x-2y) -(5x-4y)=
-(3x-2y) -(5x-4y) = -3x+2y-5x+4y = 6y-8x
To simplify the expression -(3x-2y) -(5x-4y), we can distribute the negative sign to both terms inside the parentheses:
-3x + 2y - 5x + 4y
Next, we can combine the like terms, which means adding or subtracting the coefficients of the same variables:
(-3x - 5x) + (2y + 4y)
-8x + 6y
Therefore, -(3x-2y) -(5x-4y) simplifies to -8x + 6y.
