Q. How many solutions does this equation have?9h−7=8hChoices:(A)no solution(B)one solution(C)infinitely many solutions
Isolate variable h: Isolate the variable h on one side of the equation.To do this, subtract 8h from both sides of the equation.9h−7−8h=8h−8hThis simplifies to:h−7=0
Add 7 to solve: Add 7 to both sides of the equation to solve for h.h−7+7=0+7This simplifies to:h=7
Check solution: Check the solution by substituting h=7 back into the original equation.9(7)−7=8(7)63−7=5656=56This shows that h=7 is indeed a solution to the equation.
