Solving equations is a basic skill that you must master to deal with a lot of problems in mathematics, physics, chemistry, administration, economy, and almost every activity where you need to use a formula or a model. to solve for h, you follow these steps: 1) multiply both sides by 2 => 2A = (a+b)h; 2) divide both sides by (b+a) => 2A/ (a+b) = h. So the answer is: h = 2A / (a+b).
