Answer:

d = -89

Explanation:

2d + 160 = -18

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, subtract 160 from both sides:

2d + 160 (-160) = -18 (-160)

2d = -18 - 160

2d = -178

Divide 2 from both sides:

(2d)/2 = (-178)/2

d = -178/2

d = -89

d = -89 is your answer.
