(-15/6)+x=(5/9); thrice (-5/6)=(-15/6)
\n" ); document.write( "multiply both sides by 18
\n" ); document.write( "-45+18x=10; add 45 to both sides, then divide by 18 both sides
\n" ); document.write( "18x=55
\n" ); document.write( "x=(55/18)\r
\n" ); document.write( "\n" ); document.write( "(-15/6)+(55/18)=(-45+55)/18=(10/18)=(5/9)\r
\n" ); document.write( "\n" ); document.write( "(55/18)\r
