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 ...

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars
