Question

Solve the following 2x - 13 = 9

Answer 1

Let's solve the equation by taking all the numbers to one side and variable to one side.

Remember, side change = sign change

So, we have:

`\begin{gathered} 2x-13=9 \\ 2x=9+13 \\ 2x=22 \end{gathered}`

Now, we solve for x by dividing both sides by 2:

`\begin{gathered} 2x=22 \\ (2x)/(2)=(22)/(2) \\ x=11 \end{gathered}`
