Question

8x +5y =9 3x+2y=4 by graphical method

Answer 1

Answer:

Solution = (x, y) = (-2, 5)

Step-by-step explanation:

Solution by algebraic method:

8 x + 5 y = 9    or     16 x + 10 y = 18

3 x + 2y = 4   or       15 x + 10 y = 20

So x = -2    and hence  2 y = 4 - 3 x = 10 .    y = 5.

  ie., (x,y) = (-2, 5) is the point of intersection.

Solution by graphical method is enclosed..

Draw each of the lines and then find the intersection. Then draw lines parallel to axes to identify the point.
