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

In the expression 9s – 4r – 7s + 3, like terms are terms that have the same variables raised to the same powers

In the expression 9s – 4r – 7s + 3, like terms are terms that have the same variables raised to the same powers. In this case, the variables are s and r.

Grouping the terms, we have: 9s – 7s – 4r + 3.

Now we can combine the like terms by adding or subtracting their coefficients. The coefficients are the numbers in front of the variables.

For the terms with s, we have 9s – 7s = 2s.

For the term with r, we have -4r.

Now putting it all together, the simplified expression with like terms would be: 2s – 4r + 3.
