Step 1:
Write the equation
[tex]Ax\text{ + By = C}[/tex]
Step 2:
To make x subject of the relation, you will need to solve for x.
[tex]\begin{gathered} Ax\text{ + By = C} \\ Ax\text{ = C - By} \\ \text{Divide through by A} \\ \frac{Ax}{A}\text{ = }\frac{\text{C - By}}{A} \\ \text{x = }\frac{\text{C - By}}{A} \end{gathered}[/tex]
Final answer
[tex]\begin{gathered} \text{x = }\frac{\text{C - By}}{A} \\ \text{Option C} \end{gathered}[/tex]
