 Question 323445: How do I do this? Provide an example that uses the elimination method to solve two linear equations. I do not understand this at all.......Please help me Answer by ankor@dixie-net.com(15622)   (Show Source): You can put this solution on YOUR website!Here is a recent problem solved using the elimination method We multiply one or both equations by a value that will make the coefficient of one of the variables the same, if the signs are different we can add If the signs are the same we subtract. : +8x + 7y = 12 -7x - 4y = -2 : Multiply the 1st equation by 4, multiply the 2nd equation by 7, results +32x + 28y = 48 -49x - 28y = -14 ---------------------addition eliminates y, find x -17x + 0y = 34 x = x = -2 : Use the 1st original equation to find y 8(-2) + 7y = 12 -16 + 7y = 12 7y = 12 + 16 7y = 28 y = y = 4 : : Check solution in the 2nd original equation: -7(-2) - 4(4) = -2 14 - 16 = -2
