6%28d-1%29=3%28d%2B5%29 Start with the given equation.


6d-6=3d%2B15 Distribute.


6d=3d%2B15%2B6 Add 6 to both sides.


6d-3d=15%2B6 Subtract 3d from both sides.


3d=15%2B6 Combine like terms on the left side.


3d=21 Combine like terms on the right side.


d=%2821%29%2F%283%29 Divide both sides by 3 to isolate d.


d=7 Reduce.
