3x+y=18 y=18-3x
\n" ); document.write( "2x-y=12 now substitute (18-3x) for y in this equation 7 solve for x
\n" ); document.write( "2x-(18-3x)=12
\n" ); document.write( "2x-18+3x=12
\n" ); document.write( "5x=30
\n" ); document.write( "x=30/5
\n" ); document.write( "x=6 answer now substitute 6 for x & solve for y
\n" ); document.write( "3*6+y=18
\n" ); document.write( "18+y=18
\n" ); document.write( "y=18-18
\n" ); document.write( "y=0 answer
