You can put this solution on YOUR website!
x = steve's age now
\n" ); document.write( "y = rose's age now
\n" ); document.write( "---
\n" ); document.write( "x = y + 4
\n" ); document.write( "(x + 5) + (y + 5) = 2((x - 5) + (y - 5))
\n" ); document.write( "x + 5 + y + 5 = 2(x - 5 + y - 5)
\n" ); document.write( "x + 5 + y + 5 = 2x - 10 + 2y - 10
\n" ); document.write( "x + y + 10 = 2x + 2y - 20
\n" ); document.write( "x + y = 30
\n" ); document.write( "---
\n" ); document.write( "x = y + 4
\n" ); document.write( "x + y = 30
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x - y = 4
\n" ); document.write( "x + y = 30
\n" ); document.write( "---
