Algebra.Com's Answer #10922 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! The idea is to create the same number of \"x's\" or \"y's\" in both equations. \n" ); document.write( "Then you subtract one equation from the other to eliminate that variable. \n" ); document.write( "To get rid of the \"x's\" in your problem: \n" ); document.write( "Multiply both sides of the 1st equation by 3 to get the following \n" ); document.write( "24x + 15y = 18 \n" ); document.write( "Multiply both sides of the 2nd equation by 8 to get the following \n" ); document.write( "24x - 16y = 80\r \n" ); document.write( "\n" ); document.write( "Now, subtract the new 2nd equation from the new 1st equation to get \n" ); document.write( " 31y= -62 \n" ); document.write( " y= -2 \n" ); document.write( "Substitute that value of y into either of the original equations to \n" ); document.write( "solve for x.\r \n" ); document.write( "\n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
