Solve:
`ax + by = a - b`
`bx - ay = a + b`

Solve: ax - by = 1 bx + ay = 0

The Co-ordinations of the point of intersection of lines ax + by =9 and bx + ay =5 is ( 3,-1) find the values of a and b.

"Solve for x and y; ax+by=a-b, "bx-ay=a+b

Solve: ax+by=a-b,quad bx-ay=a+b

Solve the following system of equations bx + ay = 2ab and ax - by = a^(2) - b^(2) .

Find the value of x and y by solving given linear equations ax + by = a^2 ; bx + ay = b^2

If a !=b , then the system of equation ax + by + bz = 0 bx + ay + bz = 0 and bx + by + az = 0 will have a non-trivial solution, if
