Question 21746: Hi. My name is Valeria and I need help with Algebra. Here is the problem.
7a+6b+3a
4x+2y-x+3y
I need help with those two. Please send me a step-by-step calculation please. I'm not asking for much but here are some more:
8(2a-b-3c)+ 3(2a-b)-4(6-b)
4{2a(a+3)+6(4-a)}+5a2
I don't speak algebra. This is all new to me.

You can put this solution on YOUR website! In the first two, you just have to combine like terms:
7a+6b+3a
10a + 6b
4x+2y-1x+3y
3x + 5y
In the next two, you need to remove the parentheses using the distributive property and combine like terms.
8(2a-b-3c)+ 3(2a-b)-4(6-b)
16a -8b -24c + 6a -3b -24 +4b
Combine the a terms: 16a +6a = 22a
Combine the b terms: -8b -3b +4b = -11b+4b = -7b
There is only one c term and only one number term, so they do not combine!
Final Answer= 22a -7b -24c -24
On the last problem, I would remove parentheses on the inside first:
Combine like terms inside the parentheses only:
Now,  are like terms, so they combine 
Final Answer:
If you are having a hard time speaking algebra, you might want to check out my website by clicking on my tutor name "rapaljer" anywhere in algebra.com, and look for "Basic Algebra," then look for "Samples from Basic Algebra: One Step at at Time", go to Chapter 1, and look at the section on "Combining Like Terms, The Distributive Property."
