Find values for m and b in the following system so that the solution to the sytsem is (-3,4).\r
\n" ); document.write( "\n" ); document.write( "5x+7y=b
\n" ); document.write( "mx+y=22
\n" ); document.write( "---------
\n" ); document.write( "If y=4 when x=-3 you get:\r
\n" ); document.write( "\n" ); document.write( "5(-3)+7(4) = b
\n" ); document.write( "m(-3)+4 =22\r
\n" ); document.write( "\n" ); document.write( "----------
\n" ); document.write( "Then:
\n" ); document.write( "b=-15+28 = 13
\n" ); document.write( "and
\n" ); document.write( "-3m =18
\n" ); document.write( "m=-6
\n" ); document.write( "---------
\n" ); document.write( "Solution: b=13 and m=-6
\n" ); document.write( "--------
