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(z-9)+30+z
and
4(y-3)+9-3y
-12z+4(z-9)+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.
4(y-3)+9-3y
I come out and get
4y-12+9-3y
What do I do now? I'm so confused! I don't know it !:(
Now combine like terms.
4y-12+9-3y
4y - 3y = y
9 - 12 = -3
4y-12+9-3y = y - 3
Now how would I do this? This is so confusing.

Hello! I'm here to help you with simplifying algebraic expressions. Simplifying algebraic expressions involves combining like terms and using the distributive property.
Let's start with the expression -12z + 4(z - 9) + 30 + z:
1. First, distribute the 4 to the terms inside the parentheses: -12z + 4z - 36 + 30 + z
This simplifies to: -12z + 4z - 6 + z
2. Next, combine the like terms. The terms with z are like terms, so we can combine them: -12z + 4z + z = -7z
The constant terms are also like terms, so we can combine them: -6 + 30 = 24
3. Putting it all together, the simplified expression is: -7z + 24
Now, let's move on to the expression 4(y - 3) + 9 - 3y:
1. First, distribute the 4 to the terms inside the parentheses: 4y - 12 + 9 - 3y
This simplifies to: 4y - 3y - 3
2. Next, combine the like terms. The terms with y are like terms, so we can combine them: 4y - 3y = y
The constant terms are also like terms, so we can combine them: -12 + 9 = -3
3. Putting it all together, the simplified expression is: y - 3
To simplify algebraic expressions, always make sure to:
1. Distribute any multiplication or division across the terms inside parentheses.
2. Combine like terms, which means adding or subtracting terms with the same variable and exponent.
I hope this explanation helps you understand how to simplify algebraic expressions! If you have any more questions, feel free to ask. Good luck on your test!
