4%283d-5%29=2%285d%2B1%29 Start with the given equation.



12d-20=10d%2B2 Distribute.



12d=10d%2B2%2B20 Add 20 to both sides.



12d-10d=2%2B20 Subtract 10d from both sides.



2d=2%2B20 Combine like terms on the left side.



2d=22 Combine like terms on the right side.



d=%2822%29%2F%282%29 Divide both sides by 2 to isolate d.



d=11 Reduce.

Answer:

So the solution is d=11
