Solve x + 4y = 12 for y. \r

\n" ); document.write( "\n" ); document.write( "x + 4y = 12
\n" ); document.write( "x - x +4y = 12 - x
\n" ); document.write( "0+4y = 12-x
\n" ); document.write( "4y = -x + 12
\n" ); document.write( "1/4 * 4y = 1/4 *(-x + 12)
\n" ); document.write( "1 * y = 1/4*(-x) + 1/4*(12)
\n" ); document.write( "y=-1/4 x +3 or y = -0.25x + 3
