Answer:
[tex]L = \frac{k}{4} + \frac{7}{4}[/tex]
Step-by-step explanation:
Isolate the variable, L. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS =
Parenthesis
Exponents (& Roots)

First, add 7 to both sides of the equation:
k = 4L - 7
k (+7) = 4L - 7 (+7)
k + 7 = 4L
Next, divide 4 from both sides of the equation:
(k + 7)/4 = (4L)/4
L = (k + 7)/4
L = (k/4) + (7/4)
[tex]L = \frac{k}{4} + \frac{7}{4}[/tex] is your answer.
