You can put this solution on YOUR website!
solve for y: ax+by=c\r
\n" ); document.write( "\n" ); document.write( "This is called a literal equation since there are no numbers. \r
\n" ); document.write( "\n" ); document.write( "To solve for y means to isolate y.\r
\n" ); document.write( "\n" ); document.write( "The same applies to any variable we are solving for.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "ax + by = c\r
\n" ); document.write( "\n" ); document.write( "by = c - ax\r
\n" ); document.write( "\n" ); document.write( "y = (c - ax)/b\r
\n" ); document.write( "\n" ); document.write( "NOTE: y = (-ax + c)/b is the same thing as y = (c - ax)/b.\r
\n" ); document.write( "\n" ); document.write( "We can apply the commutative rule of addition on the numerator allowing us to switch the terms around not changing the value of the entire fraction. Understand?\r
