Answer:

d = 3 1/4 or 3.25

Step-by-step explanation:

2 + d = 2 - 3 (d - 5) -2

Distribute

2+d = 2 -3d+15 -2

Combine like terms

2 +d = -3d+15

Add 3d to each side

2+d+3d = 15

2+4d = 15

Subtract 2 from each side

2+4d-2 = 15-2

4d = 13

Divide by 4

4d/4 = 13/4

d = 12/4 + 1/4

d = 3 1/4

d = 3.25
