Explain, in complete sentences, which method you would use to solve the following system of equations and why you chose that method. Show your work and provide the solution to the system. 4x + 3y = 2 3x + 2y = 1
i would ask someone on open study. they would type the question in for me into wolfram alpha and hit enter. then i would read the solution and see that \(x=-1,y=2\) http://www.wolframalpha.com/input/?i=4x+%2B+3y+%3D+2%2C3x+%2B+2y+%3D+1
lol did you make wolfram? taking the credits, eh?
this probably wil http://www.wolframalpha.com/input/?i=4x+%2B+3y+%3D+2%2C3x+%2B+2y+%3D+1l not go over so well with your teacher, so maybe we try this 1) multiply the first equation by 2 2) multiply the second equation by -3 we get \[8x+6y=4\] \[-9x-6y=-3\] 3) add them together and get \[-x=1\] 4) solve for \(x\) get \(x=-1\)
^haha I reccomend using subtraction here. Multiply the top one by 2 and the bottom by -3, and then solve by adding the equations together. The y's should cancel out. |dw:1340375128139:dw|
