Algebra.Com's Answer #120124 by soar(1) ![]() You can put this solution on YOUR website! Solve each system by elimination\r \n" ); document.write( "\n" ); document.write( "first you have to find the lowest common multiple and make sure that al variables x & y are on one side\r \n" ); document.write( "\n" ); document.write( "1)first for 3x+3=y subtract 3x to get x &y variables on one side \n" ); document.write( " -3x -3x\r \n" ); document.write( "\n" ); document.write( "2)you should get -3x+y=3 find the lowest common multiple im going to choose \n" ); document.write( " 3x+2y=6 y the lowest common multiple or lcd is 2y right but \n" ); document.write( " theres a trick you have to have a positive and \n" ); document.write( " negative value \r \n" ); document.write( "\n" ); document.write( "3)-3x+y=3 multiply by -2 to get a negative y value \n" ); document.write( " 3x+2y=6 and 1 because 2y is already positive so theyll cancel out\r \n" ); document.write( "\n" ); document.write( "4)you should have -6x-2y=-6 the y variables cancel eath other out \n" ); document.write( " 3x+2y=6\r \n" ); document.write( "\n" ); document.write( "5)when you get the x value value chose one of the original problems by plugging \n" ); document.write( "in x value into either 3x+2y=6 or 3x+3=y to get y value \n" ); document.write( " |
