You can put this solution on YOUR website!
x = mother age now
\n" ); document.write( "y = son age now
\n" ); document.write( "---
\n" ); document.write( "x = y + 25
\n" ); document.write( "x = 10 = 2(y + 10)
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x = y + 25
\n" ); document.write( "x = 10 = 2y + 20
\n" ); document.write( "---
\n" ); document.write( "x - y = 25
\n" ); document.write( "x - 2y = 10
\n" ); document.write( "---
