Solve for d 6d -11/2 = 2d -13/2. Please answer quickly

Slav-nsk [51]

6d -11/2 = 2d -13/2

Subtract 2d from both sides

6d -11/2 - 2d = 2d -13/2 - 2d

Simplifying

4d -11/2 = -13/2

Add 11/2 to both sides

4d -11/2 + 11/2 = -13/2 + 11/2

Simplifying

4d = -2/2

4d = -1

Divide both sides by 4

4d/4 = -1/4

Simplifying

d = - 1/4
