Full solution

Q. Solve for cc.\newline9+7c=8c\sqrt{9 + 7c} = \sqrt{8c}\newlinec=c = _____
  1. Square Both Sides: Square both sides of the equation to eliminate the square roots.\newline(9+7c)2=(8c)2(\sqrt{9 + 7c})^2 = (\sqrt{8c})^2\newline9+7c=8c9 + 7c = 8c
  2. Subtract to Isolate: Subtract 7c7c from both sides to isolate the variable cc on one side.\newline9+7c7c=8c7c9 + 7c - 7c = 8c - 7c\newline9=c9 = c
  3. Check Solution: Check the solution by substituting cc back into the original equation.\newline9+7×9=8×9\sqrt{9 + 7\times 9} = \sqrt{8\times 9}\newline9+63=72\sqrt{9 + 63} = \sqrt{72}\newline72=72\sqrt{72} = \sqrt{72}\newlineThis confirms that the solution is correct.
