Question

Ax + by = 1, bx + ay = 0

Answer 1

Multiply equation 1 by  b and equation 2 by a,you will get

abx+b square y=b----3
abx+a square y=0 ---4

equation 3 minus equation 4

abx+b square y - (abx+a square y) = b

abx+b square y - abx -a square y=b

b square y - a square y=b

y(b square  - a square )=b

y= b/b2-a2,substitute this value in either equation 1 or 2,you will get x= -a/b2-a2
