The equation is given by:
We are given a equation in terms of the variable m and variable n as follows:
Now, we are asked to find the equation in terms of m i.e. we have to consider m as independent variable and n as dependent variable since it's value is to be expressed in terms of m.
Now, we add 5n on both the sides of the equation to get:
Now, we subtract 7m from both the sides of the equation to get:
