Question

Solve the equation for L
k = 4L - 7

Answer 1

`L = (k)/(4) + (7)/(4)`

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.

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)

`L = (k)/(4) + (7)/(4)` is your answer.
