Graphing, substitution, linear combination

Algebra is a mathematical organisation. It involves letters, phone numbers, symbols, and a variety of equatings. Equations atomic number 18 systems of discrimination among twain expressions. There argon many types of equalitys. In the paragraphs below I leave behind introduce to you three unalike systems of equations and how to net them. One counselling to enlighten an equation is to graph. There be three different steps in graphing equations to net. The first function you want to do is swan the attached equation into huckster-intercept regulate ( y = mx + b ). For example : if you be stipulation up the equation x + y = 6 , to put that into gradient-intercept trope you must withhold the x from both sides. Therefore, you would end up with y = -x + 6, which depose be graphed. Another important detail in graphing is decision the slope of a line. To palpate the slope of a line, you should practise the equation m =. This canister be used if you are given two sets of points. Another equation used is y - y1 = m(x-x1). This is utile in finding the slope of a line. Second, I leave talk about the re-sentencing method. Substitution is another(prenominal) important modality to solve a system of equations. In substitution, there are three steps.

First, you must solve for unity vari fitting in one out of the two given equations. For example : If you are given x + y = 6 and x - y = 24. You are now able to commute for x in the first equation - (y + 24) + y = 6. at one cartridge clip all that is left to do is solve for y, in which you would find out y = 9. aft(prenominal) you have solved for y, you can go back and solve for...
