Solve by graphing:
\n" ); document.write( " $\"5u%2Bv+=+21\"$
\n" ); document.write( " $\"5u+=+v%2B29\"$
\n" ); document.write( "Rewrite the equation in slope-intercept form:
\n" ); document.write( " $\"v+=+-5u%2B21\"$
\n" ); document.write( " $\"v+=+5u-29\"$
\n" ); document.write( "Graph:
\n" ); document.write( " $\"graph%28400%2C400%2C-2%2C10%2C-5%2C5%2C-5x%2B21%2C5x-29%29\"$
\n" ); document.write( "From the graph, the solution is: (5, -4) or u = 5 and v = -4
\n" ); document.write( "The system is a consistent system since there is at least one solution.
\n" ); document.write( " \n" ); document.write( "
