Show all work to solve the equation for x. If a solution is extraneous, be sure to identify it in your final answer. Sqrt x plus 7 minus 1 equal x

  x = 2

Step-by-step explanation:

Without parentheses and appropriate math symbols, it is difficult to tell what you're trying to solve. We think it might be ...

This can be rearranged for a graphing calculator to ...

Such a calculator shows that x=2 is the solution. It also can show that x=-3 is an extraneous solution. (see the attachment)

__

The algebraic solution is to isolate the radical, then square both sides.

Trying these values of x in the equation, we get ...
