Isolate variable h: First, we need to isolate the variable h on one side of the equation. To do this, we will subtract 4h from both sides of the equation to get the terms with h on one side.Calculation: 6h−4h=4h+18−4h
Simplify equation: After subtracting 4h from both sides, we simplify the equation.Calculation: 2h=18
Solve for h: Now, we need to solve for h. To do this, we will divide both sides of the equation by 2 to isolate h.Calculation: 22h=218
Find value of h: After dividing both sides by 2, we find the value of h.Calculation: h=9
