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.
