1) what is the answer to 5(3x-2y)+2(x+2y)-3(3x-2y)?

vichka [17]

So first we want to distribute. (#1)

So, using the distributive property, we can:

5 * 3x - 2y * 5 + 2x + 2 * 2y - 3 * 3x - 3 * 2y

or

15x - 10y + 2x + 4y - 9x - 6y

Now just combine like terms

8x -12y

So for #1 it should be a.

#2: 2x - 3 + 3x - 5

Combine Like Terms:

2x + 3x - 3 - 5

5x - 8

So it should be b.
