Question

Hello this is all 1 math problem together may I get help with the solve and check .

Answer 1

The given expression is,

`7n+14=-21`

So bringing "14" to the other side of the euals,

`\begin{gathered} 7n=-21-14 \\ =-35 \end{gathered}`

On division,

`\begin{gathered} 7n=-35 \\ n=-(35)/(7)=-5 \end{gathered}`

Now, let us substitute -5 for n,

`7*(-5)=-35`

Hence checked.
