Answer: The required solution for p is

Step-by-step explanation: We are given to solve the following equation for the variable p :

To solve the given equation for p, we must take p on one side of the equation and all other terms on the other side.
From equation (i), we get
![2m=(p-q)/(r)\\\\\Rightarrow 2mr=p-q~~~~~~~~~~~~~~[\textup{Cross-multiplication}]\\\\\Rightarrow p=2mr+q.](https://img.qammunity.org/2018/formulas/mathematics/high-school/4pi4p732eub47irezw5ducctrnnij4htbw.png)
Thus, the required solution for p is
