You can put this solution on YOUR website!
hmm it goes this way....
\n" ); document.write( "the idea first is to get a combined equation of the two either by adding them or subtracting them like...:
\n" ); document.write( "i can easily subtract the two equations:
\n" ); document.write( "(1) x-4y=-2
\n" ); document.write( "(2) x+2y=4
\n" ); document.write( "subtracting will get us free from one variable 'x' cancelled out.
\n" ); document.write( "+x-4y=-2
\n" ); document.write( "+x+2y=4
\n" ); document.write( "(-)
\n" ); document.write( "__________
\n" ); document.write( "-6y=-6
\n" ); document.write( "6y=6
\n" ); document.write( "y=1
\n" ); document.write( "okkkk now v get the value of y as 1.
\n" ); document.write( "we cud put y's value in either of the equation to get the value of 'x'
\n" ); document.write( "e.g i put it in (1)
\n" ); document.write( "x-4y=-2
\n" ); document.write( "put y=1
\n" ); document.write( "x-4(1)=-2
\n" ); document.write( "x-4=-2
\n" ); document.write( "x=-2+4
\n" ); document.write( "x=2
\n" ); document.write( "so the intersecting points are (x,y)=(2,1)
\n" ); document.write( "
\n" ); document.write( "
\n" );
