Question

Please help and answer both questions would very much appreciate it

Answer 1

Step 2 is expressed as follows

`-2x-3=x-18`

To move to step 3 we have to add 2x to both sides of the equation like so

`\begin{gathered} -2x+2x-3=x+2x-18 \\ -3=3x-18 \end{gathered}`

Therefore we used addition property of the equality .
