Solve the following equation for D. Be sure to take into account whether a letter is capitalized or not. fD - 7 = q^2

Alecsey [184]

Answer:

$\displaystyle D=\frac{q^2+7}{f}$

Step-by-step explanation:

<u>Equation Solving</u>

We are given the equation:

$fD - 7 = q^2$

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:

$fD = q^2+7$

Dividing by f:

$\mathbf{\displaystyle D=\frac{q^2+7}{f}}$
