Solving formula equations or literal equations is not hard if you understand how to solve regular variable equations. When we are solving a formula equation all we are doing is writing the formula in a different way. Example, lets consider the formula Area=Base * Height written as A=BH. Now if I told you to solve this formula equation for H what I’m asking is to write the formula such that you have H= not as it’s current form as A=BH. So what does the formula look like as H=? Well we have to solve for H meaning you have to think of the variables B and A as numbers. So we have A=BH think of it as maybe 10=5H. Now if you were to solve for H you would divide both sides of the equation by 5. Well that’s what we need to do in the formula but we divide both sides of the formula not by 5 but rather B (because it’s in the same place as the 5). So H= A/B. Confused? Many students struggle with this at first but in algebra you have to practice, practice, practice to succeed! Good luck!
