x - 6y = -46
\n" ); document.write( "-3x - 7y = -62 multiply first one by 3 and add to second one
\n" ); document.write( "***
\n" ); document.write( " 3x - 18y = -138
\n" ); document.write( "-3x - 7y = -62 add them
\n" ); document.write( "************
\n" ); document.write( "-25y=-200 divide each side by -25
\n" ); document.write( "y=8
\n" ); document.write( "plug into either of the equations
\n" ); document.write( "x-6*8=-46
\n" ); document.write( "x-48=-46
\n" ); document.write( "x=2
\n" ); document.write( "(2,8)
\n" ); document.write( "
