Question

Solve for the unknown. rp = rq + r; Given r =40, p = 2

Answer 1

We have the equation:

`rp=rq+r`

We know that r = 40 and p = 2, so we have to calculate the value of q:

First, we replace the known values and then proceed to solve the equation:

`\begin{gathered} rp=rq+r \\ 40\cdot2=40\cdot q+40 \\ (40\cdot2)/(40)=(40\cdot q+40)/(40) \\ 2=q+1 \\ q=2-1 \\ q=1 \end{gathered}`

The value of the unknown variable q is q = 1
