Question 550827: Combine like terms. Use distributive property to simplify the algebraic expression. Show the work.

1. 8x+24
2. 12x -30x
3. 21x-7x

4. 36x + 15x

Whats a sentence you can se to write a simple rule that you can use to add or subtract like terms?

You can put this solution on YOUR website!
1) 8(x+3) took out the HCF
2) -18x subtracted 30x from 12x
3) 14x subtracted 7x from 21x
4) 51x added 36x with 15x
Always add like terms before continuing with the problem.
subtraction is the same as adding negative variables.
