I prefer to isolate y. \n" ); document.write( " -5(4x -5y =28) \n" ); document.write( " 4(5x +6y =14)\r \n" ); document.write( "\n" ); document.write( "-20x +25y =-140 \n" ); document.write( " 20x +24y = 56 \n" ); document.write( " The x's cancel out leaving you: \n" ); document.write( " 49y= -84 \n" ); document.write( "then divide. y=-3 \n" ); document.write( "To figure out x, you do the same thing except you don't have to use a negative number because there is already one. \n" ); document.write( "6(4x-5y=28) \n" ); document.write( "5(5x+6Y=14) \n" ); document.write( "24x -30y =168 \n" ); document.write( "25x +30y =70 \n" ); document.write( "29x=238 \n" ); document.write( "x= 4.85 \n" ); document.write( "I hope this helps.
