d=55t I need to be shown the operations to get the answer. I really don't get this

If you know the value of t, multiply it by 55 to find d.
If you know the value of d, divide both sides by 55 to find t. 
Please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in another post. Thank you.
