Algebra.Com's Answer #283466 by algebrahouse.com(1659)![]() ![]() You can put this solution on YOUR website! 2x - 3y = 12-----> -4x + 6y = -24 {multiplied top by -2} \n" ); document.write( "4x - 5y = -3------> 4x - 5y = -3 {bottom stays the same}\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "y = -27 {added the two new equations together} \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "2x - 3(-27) = 12 {substituted -27 in for y into top equation} \n" ); document.write( "2x + 81 = 12 {multiplied -3 by -27} \n" ); document.write( "2x = -69 {subtracted 81 from both sides} \n" ); document.write( "x = -69/2 {divided both sides by 2} \n" ); document.write( "www.algebrahouse.com \n" ); document.write( " |
