Find the value of the d. 2d - 5 = 17

LenKa [72]

Answer:

d = 11

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.

First, add 5 to both sides

2d - 5 (+5) = 17 (+5)

2d = 17 + 5

2d = 22

Next, divide 2 from both sides

(2d)/2 = (22)/2

d = 22/2

d = 11

11 is your answer for d.
