Can someone explain to me how to combine like terms?(7th grade) Like can you give me an example problem then tell how to solve it.

When two numbers in an equation have the same variable and or charge, then you use the commutative property to put them next to each other.

Step-by-step explanation:

Example:

4x + 2 + 3x - 1 <--- Here is the original equation.

4x + 3x + 2 - 1 <---Use the commutative property to add the like terms        

                             together. 3x and 4x end in the same variable. 2 and 1 both

                             have no variable. Therefore both of the groups are like    

                             terms.

7x + 1   <--- Add/subtract the live terms together.

8x <--- Here is your answer.

Hope this helps! :D
