You can put this solution on YOUR website!
x = girl age now
\n" ); document.write( "y = father age now
\n" ); document.write( "---
\n" ); document.write( "x = y - 27
\n" ); document.write( "x + y + 6 = 51
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x - y = -27
\n" ); document.write( "x + y = 45
\n" ); document.write( "---
\n" ); document.write( "copy and paste the above standard form linear equations in to this solver:
