document.write( "Question 81885: respected teacher,
\n" ); document.write( "i have a big problem.
\n" ); document.write( "we have not learned this yet in the class.
\n" ); document.write( "the question is: find four values of(x,y)which satisfy each of the following equations.
\n" ); document.write( "1)2x +y = 7
\n" ); document.write( "2)x - y = 3
\n" ); document.write( "3)x = -y
\n" ); document.write( "4)x = y
\n" ); document.write( "5)x + y = 11
\n" ); document.write( "6)y - 5 = x
\n" ); document.write( "i didnt understand whether we have to take every single equation in consideration or only one at a time.
\n" ); document.write( "i tried it by taking one in the consideration.
\n" ); document.write( "and for the first one got the answer:
\n" ); document.write( "2x +y = 7
\n" ); document.write( "y = 7-2x
\n" ); document.write( "so if we substitute x=3
\n" ); document.write( "then, y = 7-2*3
\n" ); document.write( "y = 7-6
\n" ); document.write( "y = 1
\n" ); document.write( "thus if x = 3,then y = 1
\n" ); document.write( "and likewise we can get other co-ordinates by substituting x\r
\n" ); document.write( "\n" ); document.write( "ps:and if this way is correct for solving this question,dont solve the other sums.just tell me it is correct
\n" ); document.write( "thanking you in anticipation,
\n" ); document.write( "your student. \n" ); document.write( "

You can put this solution on YOUR website!
your technique is correct ... also your assumption of one equation at a time \n" ); document.write( "
