2 (2d + 7)

Answer 2

Answer:

2d+17-3-2d+4d=0

reorder it

17-3+2d-2d+4d=0

combine like terms

17-3=14

14+2d-2d+4d=0

combine like terms

2d-2d=0

14+0+4d=0

14+4d=0

solving

14+4d=0

solving for variable d

move all terms containing d to the left, and all other terms to the right

14-14+4d=0-14

14-14=0

0+4d=0+(-14)

4d=0-14

0-14=-14

4d=-14

divide each by 4

d=-3.5
