Answer:
[tex]\displaystyle A=\frac{S+6}{D}[/tex]
Step-by-step explanation:
Equation Solving
To solve an equation means to isolate the required variable on the left or right side of the equal sign. Numbers and known variables should be shifted from one side of an equation to the other.
The given equation
[tex]S = AD-6[/tex]
Needs to be solved for A, meaning that we can consider S and D as known. Let's start by shifting both sides:
[tex]AD-6=S[/tex]
Adding 6 to both sides:
[tex]AD = S+6[/tex]
Dividing by D:
[tex]\boxed{\displaystyle A=\frac{S+6}{D}}[/tex]
