Solve for d.3(d − 7) − 6 = 3

Sure, let's solve the equation step by step:

1. Distribute the 3 in the expression 3(d - 7). This gives us 3d - 21.
2. So, the equation now is 3d - 21 - 6 = 3.
3. Combine like terms on the left side of the equation to get 3d - 27 = 3.
4. Add 27 to both sides of the equation to isolate the term with d. This gives us 3d = 30.
5. Finally, divide both sides of the equation by 3 to solve for d. This gives us d = 10.
