Solve for x, 10 = x+6
This type of question one has to understand that if you one thing on one side you have to do the same exact thing on the other side. As well, as you do the opposite of what it is asking for. On the right side, it is asking for a +6 so to then you have to do a -6 to get the x alone. Then you would have the same thing on the left side and 10-6 = 4, thus x = 4.

Finding the domain of a graph or equation. y = sqrt(x)
There are multiple ways of solving this question, the first being conceptually. This is assuming that the student knows that they can not sqrt a negative number and if they do then it becomes invalid. Thus, the domain has to be greater than or equal to 0. The next way would be to look at the graph, it starts at 0 and then continues on. Thus, the domain has to be greater than or equal to 0.
