Solve the equation for the bold variable

The answer to problem 14 is the equation c = 3i/e

To get this answer, you multiply both sides by 3 to undo the division of 3. Also, you divide both sides by 'e' to undo the multiplication of 'e'.

So it would look something like this

i = ec/3

3*i = 3*ec/3 ... multiply both sides by 3

3*i = ec

ec = 3i

ec/e = 3i/e ... divide both sides by e

c = 3i/e

Problem 15)

P = 2L + 2W

2L + 2W = P

2L + 2W-2L = P-2L ... subtract 2L from both sides

2W = P-2L

2W/2 = (P-2L)/2 ... divide both sides by 2

W = (P-2L)/2

So the final answer is W = (P-2L)/2
