2) To find the value of x and y complete the following activity.
equation(II)
6x + 7y = 40
equation (1); 7x + 6y = 38
Adding equations (1) and (II)
6x + 7y = 40
+ 7x + 6y 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
A
= 2 _ equation (IV)
