Question

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

Answer 1

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
