The first step for solving this equation is to divide both sides of the equation by 3.5.
2h + 4.5 = 16.5
Now move the constant to the right and then change its sign.
2h = 16.5 - 4.5
Subtract the numbers on the right side.
2h = 12
Lastly,, divide both sides of the equation by 2 to get your final answer.
h = 6
