You can put this solution on YOUR website!
x = father age now
\n" ); document.write( "y = son age now
\n" ); document.write( "---
\n" ); document.write( "x = y + 28
\n" ); document.write( "x + 11 = 3(y + 11)
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x - y = 28
\n" ); document.write( "x + 11 = 3y + 33
\n" ); document.write( "---
\n" ); document.write( "x - y = 28
\n" ); document.write( "x - 3y = 22
\n" ); document.write( "---
\n" ); document.write( "copy and paste the above standard form linear equations in to this solver:
