Square both sides: Square both sides of the equation to eliminate the square roots.(−6h+7)2=(h)2−6h+7=h
Isolate variable h: Isolate the variable h on one side of the equation.Add 6h to both sides to move the terms involving h to one side.–6h+7+6h=h+6h7=7h
Divide by 7: Divide both sides by 7 to solve for h.77=77h1=h
