2) To find the value of x and y complete the following activity.
6x + 7y=40 equation (I); 7x+6y= 38 equation(II)
Adding equations (I) and (II)
6x + 7y 40
+ 7x + 6 38
13x + 13y = 78
.. x + y = equation(III) (dividing both sides by 13)
Now subtracting equation(II) from equation (I).
.. 6x + 7y 40
7x + 6y = 38
(-)
(-)
= 2 _ equation (IV)
