Answer:

1 solution

Step-by-step explanation:

The coefficients of d are different on the two sides of the equation (3d vs 6d), so the equation has one solution.

Dividing by 3 gives ...

d +11 = 2(d +33)

d + 11 = 2d + 66

Adding -d-66 to both sides gives ...

-55 = d . . . . . . the one solution
