# Solve the followi

Given equations are , 7x— 15y = 21

Change the given equations to the form,

a1x + b1y + c1 = 0 and a2x + b2y + c2 = 0 …(i) And7x — 15y – 21 = 0

5x + 3y – 15 = 0 and 7x — 15y – 21 = 0

On comparing with (i) we get,

a1 = 5, b1 = 3, c1 = – 15; a2 = 7, b2 = – 15, c2 = – 21

Applying cross multiplication method which says, Putting the given values in the above equation we get,     Similarly,  The solution of the pair of equations is (3, 0).
