we have,
and
_________________________
__________________________
and
on adding (i) and (ii)
now, subtract (ii) from (i)
__________________________
now, we get value of a and b
and
_________________________
now, we have two equations
- 3x + y = 2 ...(iii)
- 3x - y = 4 ...(iv)
now, adding both eq.
now, substitute the value of x in (iii)
hence, value of x is 1 and value of y is -1
