Ok we are doing distributive property in math and I'm so confused on some of the problems. the problems are:

9+(x-4)
5-4x-5/-4
4(3x-2y)-3(4x-3y)
7(r+s)-(r-s)
3y-2(x-2y)

Thank you so much for your help.

• Math -

Multiply each term in parentheses by the coefficient in front of it, and then combine constants and "x" and "y" terms separately

For example,
9 + x - 4 = x + 5
(You don't even have to do a distributive multiplication on that one)

3y -2(x-2y) = 3y - 2x + 4y = 7y - 2x

You try the others.

Your second expression needs parentheses to show us what the mumerator is.

I appreciate all of your help. We had about 77 of these problems to do. These are the LAST two problems that I need some help on. Thank you so much for everything. 1/x-1 minus 2/x^2-1= -1/2 2/y plus y-1/3y= 2/5
