How does the author determine what the first compare should be? offset equation 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 descend of the two. What unaired the 2nd equation? The second equation represents the total treasure 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 deed over 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 practise the identical basic formulas for the equations. The first equation in every warning 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 examples were solv ed using different methods.

feature example used elimination. Another of the examples used substitution. Then, one of the examples the school text edition 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 collar is 6% acid. They fate to mix the two to return 60 quarts of a solution that is 5% acid. How many quarts of each should they use? permit a= quarts of Attack and b= quarts of Blast.If you want to get a full essay, order it on our website: OrderCustomPaper.com
