elminate the y's multiiply first euation by 3 and multiply 2nd equation by 2 and ad them 9x-6y=3 16x+6y=4 + 25x+0y=7 25x=7 divide both sides by 25 x=7/25 sub back 3x-2y=1 3(7/25)-2y=1 21/25-2y=1 note: 1=25/25 minus 21/25 fromboth sides -2y=4/25 divide both sides by -2 (or times -1/2) y=4/-50 y=-2/25 x=7/25 y=-2/25 (-2/25,7/25)
