Question

Solve 2 (3d + 3) = 7 + 6d.

Answer 1

Simplify and multiply:

6d+6=7+6d

Subtract 6 from both sides:

6d=1+6d

Subtract 6d from both sides:

If you do this it isn't possible

So, your answer is no solutions.

Answer 2

First distribute in the 2 on the left side to get 6d+6=7+6d

Then, you would combine the variables to be on one side of the equation by doing -6d. However, this would cancel out the d by leaving you with 0d+6=7. That is the same thing as saying 6=7.

The answer to this equation is no solution because 6 is NOT equal to 7.
