Find the value of .

d = 30

Step-by-step explanation:

Isolate the variable, d. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

Note that PEMDAS =

Parenthesis

Exponents (& roots)

Multiplication

Division

Addition

Subtraction

...and is the order in which you solve.

First, subtract 4 from both sides:

(3d)/6 + 4 = 19

(3d)/6 + 4 (-4) = 19 (-4)

(3d)/6 = 19 - 4

(3d)/6 = 15

Isolate the variable, d. Multiply 6 to both sides.

(3d)/6 x 6 = 15 x 6

3d = 15 x 6

Isolate the variable, d. Divide 3 from both sides:

(3d)/3 = 15 x (6/3)

d = (15 x (6/3) = 15 x 2 = 30)

d = 30

30 is your answer for d.
