Question

What step is needed for 2m=1+m

Answer 1

Given the below equation;

`2m=1+m`

The step that is needed is to isolate m, i.e move all the terms in m to one side of the equation. So let's go ahead and subtract m from both sides of the equation;

`\begin{gathered} 2m-m=1+m-m \\ m=1 \end{gathered}`
