\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"+7%282x%2B9%29=5%284x-15%29+\"$ Cross multiply.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"14x%2B63=20x-75\"$ Distribute.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"14x=20x-75-63\"$ Subtract $\"63\"$ from both sides.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"14x-20x=-75-63\"$ Subtract $\"20x\"$ from both sides.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"-6x=-75-63\"$ Combine like terms on the left side.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"-6x=-138\"$ Combine like terms on the right side.\r
