 Question 31074: can you show me an example of linear algebra. my question is: 2x+3y=6 2x-y=-2Answer by ikdeep(226)   (Show Source): You can put this solution on YOUR website!2x+3y=6............(1) 2x-y=-2............(2) we solve the above equations by elimination method ... 2x + 3y = 6 2x - y = -2 - + + -------------- 4y = 8 divide both sides by 4 ,,,and we get ... y = 2 putting the values of y in any of the equation to get the value of x ,,,here i am taking equation (1)..we get 2x+3y=6............(1) 2x + 3 * 2 = 6 2x + 6 = 6 subtract 6 from both sides and we get ... 2x = 0 divide both sides by 2 and we get ,,,, x = 0 therefore the value are ....y = 2 and x = 0..... Now if you want to verify you answer ,,,you can put the values of x and y in any of the equation and if you get LHS=RHS,,,this means that you answer is correct..
