Question

-3*(5х-3у)-4*(-2х+6у)

Answer 1

Відповідь:

-3(5х-3у) - 4(-2х+6у) = -15х + 9у + 8х - 24у = -7х - 15у

Покрокове пояснення:

Answer 2

$- 3(5x - 3y) - 4( - 2x + 6y) = - 15x + 9y + 8x - 24y = - 7x - 15y$

Answer 3

Let's simplify the expression step by step:

-3*(5x - 3y) - 4*(-2x + 6y)

First, distribute the -3 and -4 to the terms inside the parentheses:

-15x + 9y + 8x - 24y

Now, combine like terms:

(-15x + 8x) + (9y - 24y)

-7x - 15y

Therefore, -3*(5x - 3y) - 4*(-2x + 6y) simplifies to -7x - 15y.
