You can put this solution on YOUR website!
x = barry age
\n" ); document.write( "y = sister age
\n" ); document.write( "---
\n" ); document.write( "x = y + 8
\n" ); document.write( "x + 3 = 2(y + 3)
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x - y = 8
\n" ); document.write( "x + 3 = 2y + 6
\n" ); document.write( "---
\n" ); document.write( "x - y = 8
\n" ); document.write( "x - 2y = 3
\n" ); document.write( "---
