(-3,4)
\n" ); document.write( "5x+7y=b
\n" ); document.write( "mx+y=22 I assume this is the equation.
\n" ); document.write( ".
\n" ); document.write( "b=5*-3+7*4
\n" ); document.write( "=-15+28
\n" ); document.write( "b=13
\n" ); document.write( ".
\n" ); document.write( "-3m+4=22
\n" ); document.write( "-3m+4-4=22-4
\n" ); document.write( "-3m=18
\n" ); document.write( "-3m/-3=18/-3
\n" ); document.write( "m=-6
