Question 34905: I need to know some properties to help simplify different expressions such as:
4a+2=, 4x+x+6y-3x=, 4*3g+2(g+6k)=, 12(a+3b+6c)=
I am working on 30 different problems with nothing to guide me. I have no textbook, just a sheet of paper with Pre-Algebra problems.
Can you please give me some rules or something to follow?
Thank you, Becki Ritter

You can put this solution on YOUR website!
Well, for your problems to work they must be equal to something, for your level, a constant. You want to put the variable on one side of the equation and everything else on the other side.
For example:I will set your equations equal to 0.
4a%2B2=0 The equation
4a%2B2-2=0-2 Subtracting the constant 2 from both sides to get the term with the variable alone
4a=-2 Condensing
4a%2F4=-2%2F4 Dividing by the constant 4 to get a alone
a=-1%2F2 The answer
You can do the same things with the rest of the equations, the key is to get the variable alone.
Hope this helps if you would like further assistance feel free to contact me!
