Solve the following equation

39d+295=33d+320

Solve for d

39d + 295 = 33d + 320

Group variables

Group our variables 39d and 33d
subtract 33d from both sides

39d + 295 - 33d = 33d + 320 - 33d

6d + 295 = 320

Group constants

Group our constants 295 and 320.
subtract 295 from both sides

6d + 295 - 295 = 320 - 295

6d = 25

Divide each side of the equation by 6

 6d 6
 =
 25 6

d = 4.1666666666667

d = 4.1666666666667

d = 4.1666666666667
