As long as you perform the same operation on both sides of the equation, the equation remains balanced.
The rest is simply performing a series of arithmetic functions to break apart the complex equation in an effort to get the variable x by itself. This concept may sound daunting, but by taking away complex functions like square roots and exponents, you drastically reduce the complexity of the problem. This equation is already expressed in its simplest terms and is ready to be taken apart and solved. The basic principle behind algebra is to get the variable (x) on one side by itself and a number on the other side of the equals sign.

You just have to follow the order for completing parts of the equation and keep your work organized to avoid mistakes!
The only rule here is to make sure that what you do to one side, you do to the other. For example, if you add 29 to the left side in order to isolate t, you must also add 29 to the right side to balance the equation. In order to make sure that you have solved the problem correctly, plug your answer back into the original problem.
After performing the calculations required to solve for t, calculate the original problem by substituting t with your answer.
