You can put this solution on YOUR website!
solve 5x+4y=12 for y\r
\n" ); document.write( "\n" ); document.write( "To solve for a variable means to isolate the variable.\r
\n" ); document.write( "\n" ); document.write( "You want to place y alone on one side of the equation.\r
\n" ); document.write( "\n" ); document.write( "5x + 4y = 12\r
\n" ); document.write( "\n" ); document.write( "4y = -5x + 12\r
\n" ); document.write( "\n" ); document.write( "y = -5x/4 + 12/4\r
\n" ); document.write( "\n" ); document.write( "y = (-5x/4) + 3
\n" ); document.write( "
\n" );
