Answer 1

Method Used

→ Cross Multiplication

• Obtain both equations in form of ax + by + c.

• Take out “-” comman every time amd in every solution.

• Take comman terms out and then subtract/add the unlike terms.

• Remember y has “-” sign infront from it so it can or cannot cancel out with denoninator.

• The all three terms are equal and separate into two equations.

[I have solved each term independently]

Answer

→ x = -(a + b) & y = - 2a
