x+2y=7
\n" ); document.write( "x=7-2y now replace x in the other equation with (7-2y) & solve for y
\n" ); document.write( "3x-4y=6
\n" ); document.write( "3(7-2y)-2y=6
\n" ); document.write( "21-6y-2y=6
\n" ); document.write( "-8y=6-21
\n" ); document.write( "-8y=-15
\n" ); document.write( "y=-15/-8
\n" ); document.write( "y=15/8 or 1.875 answer.
\n" ); document.write( "x=7-2*1.875
\n" ); document.write( "x=7-3.75
\n" ); document.write( "x=3.25 answer.
