You can put this solution on YOUR website!
We could say,
\n" ); document.write( "x+.28y=.4(x+y)
\n" ); document.write( "x+.28y=.4x+.4y
\n" ); document.write( "-.12y=-.6x
\n" ); document.write( "y=5x
\n" ); document.write( "f(x)=5x\r
\n" ); document.write( "\n" ); document.write( "Now, for the given, f(x)=40=y gives x=8.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So, this is pretty simplified.\r
\n" ); document.write( "\n" ); document.write( "We can say, for example:\r
\n" ); document.write( "\n" ); document.write( "Larry needs to purchase as many 2x4s as he can with his $40. Each 2x4 costs $5. How many 2x4s can he buy?\r
\n" ); document.write( "\n" ); document.write( "The solution is found by working backward.
