Solve for x : sqrt(7x+72)+11=15 Answer:

Isolate Square Root: Isolate the square root on one side of the equation. Subtract 11 from both sides of the equation to isolate the square root. sqrt(7x + 72) + 11 - 11 = 15 - 11 sqrt(7x + 72) = 4Square Both Sides: Square both sides of the equation to eliminate the square root. (sqrt(7x + 72))^2 = 4^2 7x + 72 = 16Isolate Variable: Isolate the variable on one side of the equation to solve for x. Subtract 72 from both sides of the equation. 7x + 72 - 72 = 16 - 72 7x = -56Divide by 7: Divide both sides of the equation by 7 to solve for x. 7x / 7 = -56 / 7 x = -8

Q. Solve for

\mathrm{x}

\newline

\sqrt{7 x+72}+11=15

\newline

Answer:

Isolate Square Root: Isolate the square root on one side of the equation. $\newline$ Subtract $11$ from both sides of the equation to isolate the square root. $\newline$ $\sqrt{7x + 72} + 11 - 11 = 15 - 11$ $\newline$ $\sqrt{7x + 72} = 4$
Square Both Sides: Square both sides of the equation to eliminate the square root. $\newline$ $(\sqrt{7x + 72})^2 = 4^2$ $\newline$ $7x + 72 = 16$
Isolate Variable: Isolate the variable on one side of the equation to solve for $x$ . Subtract $72$ from both sides of the equation. $7x + 72 - 72 = 16 - 72$ $7x = -56$
Divide by $7$ : Divide both sides of the equation by $7$ to solve for $x$ . $\frac{7x}{7} = \frac{-56}{7}$ $x = -8$
