You can put this solution on YOUR website!
x = john age now
\n" ); document.write( "y = shak age now
\n" ); document.write( "---
\n" ); document.write( "y - 4 = 5(x - 4)
\n" ); document.write( "y + 2 = 2(x + 2)
\n" ); document.write( "---
\n" ); document.write( "y - 4 = 5x - 20
\n" ); document.write( "y + 2 = 2x + 4
\n" ); document.write( "---
\n" ); document.write( "5x - y = 16
\n" ); document.write( "2x - y = -2
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
