Let x=set fee and y=hourly charge
\n" ); document.write( "x+3y=125----eq1
\n" ); document.write( "and
\n" ); document.write( "x+6y=200----eq2
\n" ); document.write( "subtract eq1 from eq2:
\n" ); document.write( "3y=75
\n" ); document.write( "y=$25 per hour----hourly charge
\n" ); document.write( "substitute y=$25 into eq1:
\n" ); document.write( "x+75=125 or
\n" ); document.write( "x=$50 set fee\r
\n" ); document.write( "\n" ); document.write( "CK
\n" ); document.write( "50+75=125
\n" ); document.write( "and
\n" ); document.write( "50+6*25=200
