Square both sides: Square both sides of the equation to eliminate the square roots.(−6n+7)2=(n)2−6n+7=n
Isolate variable n: Isolate the variable n on one side of the equation.Add 6n to both sides to move the terms involving n to one side.–6n+7+6n=n+6n7=7n
Divide by 7: Divide both sides by 7 to solve for n.77=77n1=n
