the given equation are
ax+by=a-b. ........(i)
bx-ay=a+b. ........(ii)
multiplying (i) by a and (ii) by b and adding them , we get...
a^b + b^x =a^ -ab+ ab + b^
x= a^+b^÷a^b^
x=1.
substituting x=1 in equation (i), we get....
a+by= a-b
by= -b
y=-1.
Hence , x=1 and y= -1
(the symbol ^ means square which we denote by writing 2 in upper .....)
