x = greater number
\n" ); document.write( "y = smaller number\r
\n" ); document.write( "\n" ); document.write( "x + y = 128
\n" ); document.write( "x = 2y - 7\r
\n" ); document.write( "\n" ); document.write( "2y - 7 + y = 128
\n" ); document.write( "Combine like terms
\n" ); document.write( "3y - 7 = 128
\n" ); document.write( "3y - 7 + 7 = 128 + 7
\n" ); document.write( "3y = 135
\n" ); document.write( "3y/3 = 135/3
\n" ); document.write( "y = 45\r
\n" ); document.write( "\n" ); document.write( "x = 2(45)-7
\n" ); document.write( "x = 90-7
\n" ); document.write( "x = 83\r
\n" ); document.write( "\n" ); document.write( "Proof
\n" ); document.write( "83 + 45 = 128
\n" ); document.write( "
\n" );
