You can put this solution on YOUR website!
$\"5x%2B2x-9=40\"$ Start with the given equation.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"7x-9=40\"$ Combine like terms on the left side.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"7x=40%2B9\"$ Add $\"9\"$ to both sides.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"7x=49\"$ Combine like terms on the right side.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x=%2849%29%2F%287%29\"$ Divide both sides by $\"7\"$ to isolate $\"x\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x=7\"$ Reduce.\r
\n" ); document.write( "
