Question

Solve the left side and show exact steps to solve. Also, can you use algebraic terms for each step " Distributive property or Associative Multiplicative property" as of that

Answer 1

Ok, so

Given that:

`\begin{gathered} m+n=p \\ p=3r \\ m=n \end{gathered}`

We have to prove that:

`3r=2n`

Notice that if m = n, then,

`\begin{gathered} m+n=p \\ n+n=p \\ 2n=p \end{gathered}`

We also know that p=3r, so:

`\begin{gathered} 2n=p=3r \\ \end{gathered}`

Therefore,

`3r=2n`
