### Question 9. Solve the following simultaneous equation. 49x – 57y = 172; 57x – 49y = 252

Question 9.

Solve the following simultaneous equation.

49x – 57y = 172; 57x – 49y = 252

Answer:  Adding both the Equations Dividing both sides by 106 …(III)

Subtract equation (I) and (II) Divide both sides by (–8) …(IV)

Equating Eq. (III) and (IV)   Substituting x=7 in Eq. IV   ∴ solution is (x, y) = (7,3)
