collecting like terms

In algebra, the collection of like terms is a process where we simplify an algebraic expression. We do this by collecting similar terms together.

For example, there are similar terms in the expression 4x + 2 + 2x + 7. We can collect the x terms together to get 6x, and collect the numbers together to get 9.

Therefore, after collecting the terms, we can see that 6x + 9 is the simplified expression.
