You can put this solution on YOUR website!
x = jess age now
\n" ); document.write( "y = gaby age now
\n" ); document.write( "---
\n" ); document.write( "x = y + 21
\n" ); document.write( "x - 9 = 4(y - 9)
\n" ); document.write( "---
\n" ); document.write( "x = y + 21
\n" ); document.write( "x - 9 = 4y - 36
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x - y = 21
\n" ); document.write( "x - 4y = -27
\n" ); document.write( "---
\n" ); document.write( "copy and paste the above standard form linear equations in to this solver:
