Question

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

​

Answer 1

`\displaystyle D=(q^2+7)/(f)`

Explanation:

Equation Solving

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=(q^2+7)/(f)}`
