To solve a system of equations by addition or subtraction (or elimination)‚ you must eliminate one of the variables so that you could solve for one of the variables. First‚ in this equation‚ you must look for a way to eliminate a variable (line the equations up vertically and look to see if there are any numbers that are equal to each other). If there is lets say a –2y on the top equation and a –2y on the bottom equation you could subtract them and they would eliminate themselves by equaling zero

Tricking children into behaving well in order to receive presents. Isn’t that bribery? Parents say that you should never lie and always tell the truth‚ but the way I see it is‚ they have gone against their word and become a hypocrite. On the other hand they could be enhancing enjoyment. But I know‚ even now Santa is not real my enjoyment at Christmas has

method for solving linear simultaneous equations. It makes use of determinants and so a knowledge of these is necessary before proceeding. 1. Cramer’s Rule - two equations If we are given a pair of simultaneous equations a1 x + b1 y = d1 a2 x + b2 y = d2 then x‚ and y can be found from d1 b1 d2 b2 a1 b1 a2 b2 a1 d1 a2 d2 a1 b 1 a2 b 2 x= y= Example Solve the equations 3x + 4y = −14 −2x − 3y = 11 Solution Using Cramer’s rule we can write the solution as the ratio of two determinants. −14

How do I write a report? Report writing differs from essay writing because it has a different purpose. Reports are common communication tools as they assist in the decision-making process. Written for a particular purpose‚ they usually outline a problem‚ provide the relevant facts and ideas related to the situation‚ and then recommend a course of action. Reports are highly structured so that information they contain can be easily understood. Headings within the report allow the reader to select

Aaron Griffin Math 4091A March 17‚ 2015 The Cartesian Coordinate System Linear inequalities (statements such as “4≤X+10<18”) can be represented graphically along a number line. In similar manner‚ a linear equation in two variables (this being the form ax+by=c) can also be represented graphically‚ using two axes; the x axis‚ the horizontal plane‚ and the y axis‚ the vertical plane. There are memory tricks with which to distinguish the x from the y axis and remember their horizontal and vertical
