4 apples add 2 bananas add 1 apple
5 appples add 2 bananas
Similarly:-
4a + 2b + a
= 5a + 2b

Since there are two numbers with the same variable, you can add those together.
4a + a = 5a
You end up with 5a + 2b.

Here we go:
4a+2b+a
First, you group like terms
Use the communitive property (i think) to rearrange the problem. Since they both 4a and a have common variables you put it like this
4a+a+2b
4a+a+2b is the same as 4a+1a+2b, which is 5a+2b.
5a+2b is your answer.
Good luck

put all the a's together: 4a+a = 5a
put all the b's together: 2b
put everything together: 5a+2b

4a+2b+a = 5a + 2b
You can't go any further.

4a+a=5a
5a+2b
If you divide by 2 it's 2.5A+B or you can divide per 5 (A+2/5B) but no more than that...
Greetings!
