You can put this solution on YOUR website! e = K(D-d)/f
Since most folks don't particularly like FRACTIONS, I recommend you multiply both sides by the denominator f.
ef=K(D-d)
Next, remove the parentheses using the distributive property:
ef =KD - Kd
To solve for D, you need to get the D term alone on the right side. Do this by adding +Kd to each side:
ef+Kd = KD
Finally, to get D by itself, divide both sides by K:
By the way, don't DARE divide out the K's, since the K in the numerator is in a TERM!!
If you need additional help with Literal Equations, check out my website by doing a "Bing" search for my last name "Rapalje". Look for "Rapalje Homepage" at the top of the search list, and choose the link on my homepage "MATH IN LIVING COLOR." The topic of Literal Equations can be found at ALL three levels. For "College Algebra" look in Chapter 1. For "Intermediate Algebra" look in Chapter 2, and in "Basic Algebra" look in Chapter 3. My non-traditional explanation should be easier to understand than your textbook!
