Question

Simplify the expression by combining like terms: 7c+4+6c−3+9c−1.

Answer 1

The expression shown is

`7c+4+6c-3+9c-1`

There are terms with the variable 'c' and constant terms.

We can combine like terms and simplify the expression.

First, let's write the 'c' terms and constant terms separately in parenthesis. So,

`\begin{gathered} 7c+4+6c-3+9c-1 \\ =(7c+6c+9c)+(4-3-1) \end{gathered}`

Now, we can simply "add/subtract". The answer is shown below:

`\begin{gathered} (7c+6c+9c)+(4-3-1) \\ =22c+0 \\ =22c \end{gathered}`Answer22c
