2 - 3d = 4d - 19 Answer and show steps

defon

2 - 3d = 4d - 19

Add the opposite to both sides to get the variable on the left side only.

2 - 3d = 4d - 19

-4d -4d

2 - 7d = - 19

Then get the terms w/o variables on the right,

2 - 7d = - 19

-2 -2

-7d = -21

Then divide by the number paired with the variable.

--7d = -21

----- ----- ; d = 3

-7 -7

Final answer = 3
