If the system \r \n" ); document.write( "\n" ); document.write( "4x - 6y = 4 \n" ); document.write( "24x - 8y = -1 \n" ); document.write( "is to be solved using the addition method, by what constant should one of the equations be multiplied if the x terms are to drop out? \n" ); document.write( "---------- \n" ); document.write( "Multiply the 1st equation by -6 so it will look like the following: \n" ); document.write( "-24x + 36y = -24 \n" ); document.write( "--------- \n" ); document.write( "Now when you add that equation to 24x-8y=-1 you should notice \n" ); document.write( "that you get no x terms. \n" ); document.write( "That allows you to solve for y. \n" ); document.write( "================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
