Question

Solution :
Method (II
SX -
(1)
(II)
3x +
sides
of
Let u
of x fron
P=
Method I 5x – 31 = 8. .
3x + 1 = 2
Multiplying both
equation (II) by 3.
9x + 3y = 6 ... (III)
Sr 3y = 8. (1)
Now let us add equations (1)
and (III)
Sx - 3y = 8
+ 9x + 3y = 6
Subs
equc
14x = 14
x = 1
substituting r = ' in equation (II)
3x + y = 2
3 x1 + y = 2
3+ y = 2
V =
-1
solution is r = 1, y = -1; it is also
written as (x, y) = (1, -1)​
