Hello! I am needing some help on Algebra! It is hard !
Can you explain how to Simplify Algebraic Expressions? The easiest way? I have a test over it Friday, and i can't understand it at all!
Can you help with these and explain?
12z+4(z9)+30+z
and
4(y3)+93y

Math 
Ms. Sue,
12z+4(z9)+30+z
Combine like terms.
12z + 4z  36 + 30 + z
7z  6
Follow the same procedure for the next problem. I'll be glad to check your answer. 
Math 
Megan,
4(y3)+93y
I come out and get
4y12+93y
What do I do now? I'm so confused! I don't know it !:( 
Math 
Ms. Sue,
Now combine like terms.
4y12+93y
4y  3y = y
9  12 = 3
4y12+93y = y  3 
Math 
Megan,
Now how would I do this? This is so confusing.
