Answer:
[tex]\displaystyle D=\frac{q^2+7}{f}[/tex]
Step-by-step explanation:
Equation Solving
We are given the equation:
[tex]fD - 7 = q^2[/tex]
It's required to solve the equation for D. All letters must preserve their capitalization.
We must isolate the letter D by removing from the left side all the terms and coefficients that surround it.
Adding 7:
[tex]fD = q^2+7[/tex]
Dividing by f:
[tex]\mathbf{\displaystyle D=\frac{q^2+7}{f}}[/tex]
