How does the author determine what the first compare should be? commencement exercise comparability is an equation is an equation that represents the ingrained number of objects in the problem, such as x+ y=t. x and y are variables in equation and t represents the inwardness of the two. What burn down the 2nd equation? The second equation represents the total rate of the objects in equation one. The author plugs into the equation the value of individually variable. Once you continue to solve this equation it will accord in the values of the x variable and the y variable. You toilet plug the result from the 2nd equation into your first equation to check your answers. How are the illustrations similar? They all enjoyment the handle basic formulas for the equations. The first equation in every sheath is the total objects in the problem and each of the second equations represents the total amounts and solves for the variables. How are they different? The exa mples were solved using different methods.

sentience example used elimination. Another of the examples used substitution. Then, one of the examples the school school text suggested you could use elimination or substitution. Example to solve from text: Kings Service station uses two kinds of cleansing spot solutions containing acid and water. Attack is 2% acid and onrush is 6% acid. They sine qua non to mix the two to return 60 quarts of a solution that is 5% acid.
