Question

-2(5x-3y) + 3(4x-2y) с подробным решением!

Answer 1

-10x+6y+12x-6y = (-10x+12x)+(6y-6y)= 2x+0=2x

Answer 2

To simplify the expression -2(5x - 3y) + 3(4x - 2y), you'll need to apply the distributive property, which states that a(b + c) = ab + ac.

Let's go step by step:

1. First, distribute -2 into (5x - 3y): -2(5x - 3y) = -2 * 5x + (-2) * (-3y) = -10x + 6y

2. Next, distribute 3 into (4x - 2y): 3(4x - 2y) = 3 * 4x + 3 * (-2y) = 12x - 6y

Now, the simplified expression will be the sum of these two terms:

-10x + 6y + 12x - 6y

Notice that the middle terms (-6y and +6y) cancel each other out. So, the simplified expression is:

-10x + 12x

Now, combine the x-terms:

-10x + 12x = 2x

The final simplified expression is 2x.
