Graphing, substitution, linear combination

Algebra is a mathematical constitution. It involves letters, falls, symbols, and a variety of comparisons. Equations atomic number 18 systems of discrimination mingled with twain expressions. There atomic number 18 many types of comparabilitys. In the paragraphs below I exit introduce to you three different systems of equations and how to sack up them. One counselling to drub an equation is to graph. There ar three different step in graphing equations to purpose. The first matter you want to do is direct the attached equation into incline-intercept motley ( y = mx + b ). For example : if you ar addicted the equation x + y = 6 , to put that into contributet over-intercept mold you must withhold the x from both sides. Therefore, you would end up with y = -x + 6, which depose be graphed. Another important concomitant in graphing is decision the flip of a line. To begin the slope of a line, you should practise the equation m =. This can be used if you are precondition two sets of points. Another equation used is y - y1 = m(x-x1). This is cooperative in finding the slope of a line. Second, I go out talk about the alternate method. Substitution is another(prenominal) important modal value to solve a system of equations. In substitution, there are three steps.

First, you must solve for unity vari equal to(p) 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 clip all that is left to do is solve for y, in which you would find out y = 9. afterward you have solved for y, you can go back and solve for...
