x+x+x+x is Equal to 4x?

In algebra, combining like terms involves simplifying expressions by grouping together terms that have the same variable and then performing the necessary operations.

Let's break down the expression "x+x+x+x" and simplify it step by step:

x+x+x+x

Here, each term is x, and there are four of them. To simplify, you can add them together:

1x+1x+1x+1x

Combine the coefficients (the numbers in front of x):

(1+1+1+1)_x_

Simplify the sum:

4x

So, x+x+x+x simplifies to 4x. This process involves recognizing like terms (terms with the same variable, in this case, x) and combining them to express the simplified form of the expression.
