Algebra.Com's Answer #393239 by jankiz(13)![]() ![]() You can put this solution on YOUR website! First, you plug in y=3x into 2x-4y=2. So, 2x-4(3x)=2. Multiply 3x by 4. \n" ); document.write( "2x-12x=2. Subtract. -10x=2. Divide. You get x=-.2. Then plug that into one of the first equations. So, y=3(-.2). Multiply,and you get y=-.6. The solution set is (-.2,-.6), or in fraction form (-1/5,-3/5)! \n" ); document.write( " |
