Expert Answer
The question should be like below:
Solve for x and y:
ax + by - 2a + 3b = 0
And. bx - ay = 3a + 2b
Consider,
ax + by = 2a - 3b ...(i)
bx - ay = 3a + 2b ...(ii)
Multuplying by b to equation (i) and by a to equation (ii)
abx + b2y = 2ab - 3b2 ...(iii)
abx - a2y = 3a2 + 2ba ...(iv)
Subtracting (iv) from (iii) we get y = -3
Put y = -3 in (i) we get x = 2
