5x-10y=90 Solve for y?

\r\n" );
document.write( "   5x-10y = 90 \r\n" );
document.write( "\r\n" );
document.write( "Since you want to solve for y, get all terms off the left side \r\n" );
document.write( "except the -10y.  You want to get rid of the 5x term on the left.\r\n" );
document.write( "\r\n" );
document.write( "To do that, add -5x to both sides:\r\n" );
document.write( "\r\n" );
document.write( "  5x-10y = 90\r\n" );
document.write( " -5x         -5x\r\n" );
document.write( "----------------\r\n" );
document.write( "    -10y = 90-5x\r\n" );
document.write( "\r\n" );
document.write( "Divide every number on both sides by -10\r\n" );
document.write( "\r\n" );
document.write( "   \r\n" );

document.write( "\r\n" );
document.write( "Since you might want it in slope-intecept form y = mx+b you might\r\n" );
