Answer:
ax + by = a - b----- eqn 1
bx - ay = a + b -----eqn 2
eqn 1 * b
eqn 2 * a
abx + b²y = ab - b² ----eqn 3
abx - a²y = a² + ab ----- eqn 4
3 - 4
abx + b²y = ab - b²
- abx + a²y = - a²- ab
=> a²y + b²y = -a² - b²
y( a² + b²) = -a² - b²
y = -1
Eqn 2
bx - ay = a+ b
bx - a(-1) = a + b
bx + a = a + b
bx + a - a = b
bx = b
x = b/b
x =1
y = -1
