y=-x+5
\n" ); document.write( "x-4y=10
\n" ); document.write( "---
\n" ); document.write( "Substitute for \"y\" and solve for \"x\":
\n" ); document.write( "x - 4(-x+5) = 10
\n" ); document.write( "x +4x-20 = 10
\n" ); document.write( "5x = 30
\n" ); document.write( "x = 6,
\n" ); document.write( "----
\n" ); document.write( "Solve for \"y\":
\n" ); document.write( "y = -x+5
\n" ); document.write( "y = -6+5
\n" ); document.write( "y = -1
