You can put this solution on YOUR website!
x = brother age now
\n" ); document.write( "y = sister age now
\n" ); document.write( "---
\n" ); document.write( "x + 4 = 2(y + 4)
\n" ); document.write( "x + y = 46
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x + 4 = 2y + 8
\n" ); document.write( "x + y = 46
\n" ); document.write( "---
\n" ); document.write( "x - 2y = 4
\n" ); document.write( "x + y = 46
\n" ); document.write( "---
\n" ); document.write( "copy and paste the above standard form linear equations in to this solver:
