which are the intersection points of
\n" ); document.write( "2x -y =3
\n" ); document.write( "If x = 0, y = -3
\n" ); document.write( "If y = 0, x = 3/2
\n" ); document.write( "Plot (0,-3) and (3/2,0) and draw a line thru them.
\n" ); document.write( "-----------
\n" ); document.write( " x + y=6
\n" ); document.write( "If x = 0, y = 6
\n" ); document.write( "If y = 0, x = 6
\n" ); document.write( "Plot (0,6) and (6,0) and draw a line thru them.
\n" ); document.write( "----
\n" ); document.write( "Find the intersection::
\n" ); document.write( "y = 2x-3
\n" ); document.write( "y = 6-x
\n" ); document.write( "----
\n" ); document.write( "2x-3 = 6-x
\n" ); document.write( "3x = 9
\n" ); document.write( "x = 3, y = 3
\n" ); document.write( "------\r
\n" ); document.write( "\n" ); document.write( "b) x +3y = 18 ; 2x+ y = 11
\n" ); document.write( "y = (-1/3)x + 6
\n" ); document.write( "y = -2x+11
\n" ); document.write( "----
\n" ); document.write( "Solve for \"x\"::
\n" ); document.write( "(-1/3)x + 6 = -2x+11
\n" ); document.write( "(5/3)x = 5
