Question

please solve the question step by step.​

Answer 1

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
