Question

What is 9k - 2K + 5 + 7

Answer 1

Question 2:

`9K-2K+5+7=`

Let us simplify the above expression

The terms are already combined so we just need to simplify them

`\begin{gathered} 9K-2K+5+7 \\ 7K+5+7 \\ 7K+12 \end{gathered}`

Question 3:

`3-5y+6=`

Let us simplify the above expression

Combine the like terms together and simplify

`\begin{gathered} 3-5y+6 \\ 3+6-5y \\ 9-5y \end{gathered}`

Question 4:

`7r-r=`

Let us simplify the above expression

Simply subtract r from 7r

`\begin{gathered} 7r-r \\ 6r \end{gathered}`

Therefore, the simplified expressions are

`\begin{gathered} 2.\: \: 9K-2K+5+7=7K+12 \\ 3.\: \: 3-5y+6=9-5y \\ 4.\: \: 7r-r=6r \end{gathered}`
