The problem seems to have an error, I assume you meant:
\n" ); document.write( " \"two times a second number minus three times the first number is 1.\"
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement.
\n" ); document.write( ":
\n" ); document.write( "\"the sum of two numbers is 13.\"
\n" ); document.write( "x + y = 13
\n" ); document.write( "or
\n" ); document.write( "x = (13 - y)
\n" ); document.write( "or
\n" ); document.write( "y = (13 - x)
\n" ); document.write( ":
\n" ); document.write( "\"two times a second number minus three times the first number is 1\"
\n" ); document.write( "2y - 3x = 1
\n" ); document.write( ":
\n" ); document.write( "what are the two numbers?
\n" ); document.write( ":
\n" ); document.write( "Substitute (13-x) for y in the above equation and you have:
\n" ); document.write( "2(13-x) - 3x = 1
\n" ); document.write( "26 - 2x - 3x = 1
\n" ); document.write( "-5x = 1 - 26
\n" ); document.write( "x = -25/-5
\n" ); document.write( "x = + 5
\n" ); document.write( ":
\n" ); document.write( "y = (13 - 5) = 8
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution using the statement:
\n" ); document.write( " \"two times a second number minus three times the first number is 1. \"
\n" ); document.write( "2(8) - 3(15) = 1
\n" ); document.write( ":
\n" ); document.write( "If this is not what you meant, let me know, the problem can be done that way
\n" ); document.write( "You would have:
\n" ); document.write( "2y - 3y = 1
\n" ); document.write( "-y = 1
\n" ); document.write( "y = -1
\n" ); document.write( ":
\n" ); document.write( "Then:
\n" ); document.write( " x + (-1) = 13
\n" ); document.write( "x = 13 + 1
\n" ); document.write( "x = 14
\n" ); document.write( "
\n" ); document.write( "
\n" );
