Question

-4(-2х+3у) -3(5х -2у)

Answer 1

Ответ:

-4(-2х+3у)  -3(5х -2у)=-7х-6у

1)-4(-2х+3у) = 8х-12у

2) -3(5х -2у)= -15х+6у

3)8х-12у -15х+6у=-7х-6у

Answer 2

To simplify the expression -4(-2x + 3y) - 3(5x - 2y), you can use the distributive property (also known as the FOIL method for multiplying binomials). Here's how to do it step by step:

1. Distribute the -4 to both terms inside the first parentheses: -4 * (-2x) + (-4) * (3y)

2. Distribute the -3 to both terms inside the second parentheses: -3 * (5x) - 3 * (-2y)

Now, perform the multiplications:

1. -4 * (-2x) = 8x -4 * (3y) = -12y

2. -3 * (5x) = -15x -3 * (-2y) = 6y

Now, combine like terms:

8x - 12y - 15x + 6y

Now, combine the x and y terms:

(8x - 15x) + (-12y + 6y)

Simplify further:

-7x - 6y

So, the simplified expression is -7x - 6y.
