How do I simplify the following expressions by collecting like terms?
2x-9+x=?
6x-4j+3y=?
4x+15+2x-x+9+?
j-k-j+3k=
5r+3r+4rt=
7yz+yz=
If you answer the question I posed for you in your last question, I'll be happy to help you with these questions.
Oh sorry that is what it said but what you put was right
Thank you =]
To simplify an expression by collecting like terms, you need to identify the terms with the same variable(s) and combine them. Here's how to simplify each expression:
1. 2x-9+x:
To collect like terms, add the coefficients of x: 2x + x = 3x.
The expression simplifies to 3x - 9.
2. 6x-4j+3y:
There are no like terms, so the expression remains as it is.
3. 4x+15+2x-x+9:
Start by adding the coefficients of x: 4x + 2x - x = 5x.
Also, combine the constant terms: 15 + 9 = 24.
The expression simplifies to 5x + 24.
4. j-k-j+3k:
Combine the like terms with j and k separately:
j - j = 0, and -k + 3k = 2k.
The expression simplifies to 2k.
5. 5r+3r+4rt:
Add the coefficients of r: 5r + 3r = 8r.
The expression remains the same, as there is no other like term.
6. 7yz+yz:
Add the coefficients of yz: 7yz + yz = 8yz.
The expression simplifies to 8yz.
Remember to combine only the terms that have the same variables and exponents.
