I'm a school bus driver and want to know how to solve this problem handed to me from one of the students. -4x + 5y = 37.
\n" ); document.write( "----------
\n" ); document.write( "It's 1 equation in 2 variables, x & y.
\n" ); document.write( "You can pick any value for x and find y, or vice versa.
\n" ); document.write( "----
\n" ); document.write( "There are an infinite # of solutions, no unique solution.
\n" ); document.write( "------
\n" ); document.write( "eg,
\n" ); document.write( "x = 0 --> y = 37/5
\n" ); document.write( "x = 1 --> y = 41/5
\n" ); document.write( "etc
\n" ); document.write( "--------------
\n" ); document.write( "If you graph it, you get a straight line of infinite length, and every point on the line is a \"solution\" of the equation.
\n" ); document.write( "------
\n" ); document.write( "-4x + 5y = 37
\n" ); document.write( "You can solve for x in terms of y:
\n" ); document.write( "-4x = -5y + 37
\n" ); document.write( "x = (5/4)y - 37/4
\n" ); document.write( "=====================
\n" ); document.write( "or y in terms of x
\n" ); document.write( "5y = 4x + 37
\n" ); document.write( "y = (4/5)x + 37/5 \n" ); document.write( "
\n" );
