2(1,5x-y)-4(2,5x-0,5y)=3х-2у-10х+2у=-7х

Answer 2

$2(1.5x - y) - 4(2.5x - 0.5y) = 3x - 2y - 10x - 2y =3x - 10x = \boxed{ - 7x}$

Answer 3

To simplify the expression 2(1.5x - y) - 4(2.5x - 0.5y), you can distribute the constants inside the parentheses and then combine like terms. Here's how you do it step by step:

1. Distribute the constants inside the parentheses: 2 * 1.5x - 2 * y - 4 * 2.5x + 4 * 0.5y

2. Multiply the constants: 3x - 2y - 10x + 2y

3. Now, combine like terms by adding or subtracting coefficients of the same variables: (3x - 10x) + (-2y + 2y)

4. Simplify further: -7x + 0y

Since the term involving "y" cancels out (2y - 2y = 0), the simplified expression is: -7x
