What on earth is 7 + √(x - 1) = 2?<br> I'm confused...
Gala2k [10]

Answer: x = 26

Step-by-step explanation:

Let's go step by step.

7 + \sqrt{x-1} = 2\\\sqrt{x-1} = -5\\x-1 = (-5)^2 \\x-1 = 25\\x = 26

Check your answer.

7 + \sqrt{26-1} = 2\\ 7+5 = 2\\12 = 2

That clearly doesn't work, showing how it has no solution.

^The answer above explained it better than me :P
