Identifying and Combining Like Terms: Simplifying the Expression 9s – 4r – 7s + 3

Like terms in the expression 9s – 4r – 7s+ 3

In the given expression 9s – 4r – 7s + 3, we have two variables s and r

In the given expression 9s – 4r – 7s + 3, we have two variables s and r. Like terms are terms that have the same variable(s) raised to the same power(s).

The like terms in this expression are terms that involve the variable s or the variable r.

Let’s identify the like terms in the expression:

First, we have 9s and -7s. Both terms involve the variable s raised to the power of 1. These terms are like terms.

Next, we have -4r. This term involves the variable r raised to the power of 1.

Finally, the term 3 does not involve any variables. It is a constant term.

So, the like terms in the expression are 9s, -7s, and -4r.

To simplify the expression by combining like terms, we add the coefficients of the like terms and keep the variable part the same.

The simplified expression is:
(9s – 7s) – 4r + 3

Combining the like terms, we get:
2s – 4r + 3.
