Explanation:
The given equation is
![6q=3s-9](https://img.qammunity.org/2020/formulas/mathematics/middle-school/omekw3jkx48kbc52ne2klw5bv1ggo55p5x.png)
Here, q is dependent variable and s in independent variable because for different values of s, there will be different values of q. Hence, value of q depends on the value of s and hence q is dependent variable.
Now, we have yo find the equation, in which q is the independent variable. Thus, we solve the equation for s.
Add 9 to both sides of the equation
![6q+9=3s](https://img.qammunity.org/2020/formulas/mathematics/middle-school/lntin981vvatjyjbmj60qtjglhlnf1na6l.png)
Now, divide both sides by 3
![s=2q+3](https://img.qammunity.org/2020/formulas/mathematics/middle-school/fpa5d5hj7ym92fsnagzd22xnwnlrk1nugl.png)
Therefore, the equation is
![s=2q+3](https://img.qammunity.org/2020/formulas/mathematics/middle-school/fpa5d5hj7ym92fsnagzd22xnwnlrk1nugl.png)
