Answer :

To eliminate y, we have to make the coefficient of y in both the equations equal, so we have to multiply the coefficient of y with such a number that makes them equal to the common multiple of both of them.

In this case, equation 7x – 5y + 2 = 0 should be multiplied by 3 such that the coefficient of y will be equal to 15 in both the cases.
