3x + 2y = -10
\n" ); document.write( "x= 1 - 5y
\n" ); document.write( "-----
\n" ); document.write( "Rearrange:
\n" ); document.write( "3x + 2y = -10
\n" ); document.write( "x + 5y = 1
\n" ); document.write( "------
\n" ); document.write( "Modify for subtraction:
\n" ); document.write( "3x + 2y = -10
\n" ); document.write( "3x + 15y= 3
\n" ); document.write( "------
\n" ); document.write( "Subtract and solve for \"y\":
\n" ); document.write( "13y = -13
\n" ); document.write( "y = -1
\n" ); document.write( "-----
\n" ); document.write( "Solve for \"x\":
\n" ); document.write( "x = 1 - 5y
\n" ); document.write( "x = 1 - 5*-1
\n" ); document.write( "x = 1 + 5
