ax+by= a-b
bx-ay = a+b
SUBTRACT BOTH THE EQUATION AND THEN ADD BOTH THE EQUATION
YOU WILL GET 2 OTHER EQUATION ADD THEN AND VALUES OF X and Y will come

Ax+by=a-b
ax=a-b-by
x=a-b-by/a←
bx-ay=a+b
substituting
b(a-b-by/a)-ay=a+b
ab-b²-b²y/a-ay=a+b
ab-b²-b²y-a²y/a=a+b
ab-b²-(b²+a²)y=a²+ab
-(b²+a²)y=a²+ab-ab+b²
(b²+a²)y=-(a²+b²)
y=-(a²+b²)/a²+b²
y=-1←
substituting value of y
x=a-b-b(-1)/a
x=a-b+b/a
x=a/a
x=1
Happy to help Rujula
