The sum of two numbers is 89.
\n" ); document.write( "x + y = 89
\n" ); document.write( "x = (89-y)
\n" ); document.write( ":
\n" ); document.write( " Adding four times the first number to the second number gives 155.
\n" ); document.write( "4x + y = 155
\n" ); document.write( ":
\n" ); document.write( "y = 155 - 4x; is one of the possible equations
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "To solve it, substitute (89-y) for x:
\n" ); document.write( "y = 155 - 4(89-y)
\n" ); document.write( ":
\n" ); document.write( "y = 155 - 356 + 4y
\n" ); document.write( ":
\n" ); document.write( "y - 4y = -201
\n" ); document.write( ":
\n" ); document.write( "-3y = -201
\n" ); document.write( "y = \"%28-201%29%2F%28-3%29\"
\n" ); document.write( "y = +67; and x = (89-67) = 22\r
\n" ); document.write( "\n" ); document.write( "
