Question

solve -5sqrt x-9-7=23

Answer 1

Is it \[-5\sqrt{x - 9} - 7 = 23\]

Answer 2

yes :)

Answer 3

ALright.
\[-5\sqrt{x - 9} - 7 = 23 \implies -5\sqrt{x - 9} = 30 \implies \sqrt{x - 9} = -6\]At this point, notice how it's negative. Since you have a square root, the solution can never be negative, so it's no solution :)
