Question

Plot the solution of the equation on the number line

Answer 1

Step-by-step explanation:

Given the equation:

`7x+7=-14`

First, subtract 7 from both sides:

`\begin{gathered} 7x+7-7=-14-7 \\ 7x=-21 \end{gathered}`

Next, divide both sides by 7:

`\begin{gathered} (7x)/(7)=-(21)/(7) \\ x=-3 \end{gathered}`

The solution of the equation on the number line is shown below:
