solve 2x-3y=-25
\n" ); document.write( "3x+y=1 by substitution
\n" ); document.write( "------
\n" ); document.write( "Here's one way:
\n" ); document.write( "y = (2x+25)/3
\n" ); document.write( "y = (1-3x)
\n" ); document.write( "-----
\n" ); document.write( "Substitute y for y:
\n" ); document.write( "1-3x = (2x+25)/3
\n" ); document.write( "3-9x = 2x+25
\n" ); document.write( "11x = -22
\n" ); document.write( "x = -2
\n" ); document.write( "----
\n" ); document.write( "Solve for \"y\":
\n" ); document.write( "y = 1-3x
\n" ); document.write( "y = 1-3*-2
\n" ); document.write( "y = 7
