Full solution

Q. Solve for cc.\newline7c8=5c\sqrt{7c - 8} = \sqrt{5c}\newlinec=c = _____
  1. Square both sides: Square both sides of the equation to eliminate the square roots.\newline(7c8)2=(5c)2(\sqrt{7c − 8})^2 = (\sqrt{5c})^2\newline7c8=5c7c − 8 = 5c
  2. Subtract to combine terms: Subtract 5c5c from both sides to get the cc terms on one side.\newline7c5c8=5c5c7c - 5c - 8 = 5c - 5c\newline2c8=02c - 8 = 0
  3. Add to isolate term: Add 88 to both sides to isolate the term with cc. \newline2c8+8=0+82c - 8 + 8 = 0 + 8\newline2c=82c = 8
  4. Divide to solve for c: Divide both sides by 22 to solve for cc.2c2=82\frac{2c}{2} = \frac{8}{2}c=4c = 4
