To solve a simultaneous equation using elimination method, you eliminate one variable first.

Before you can do that, the coefficient of one of the variable in the two equations must be same.

From the questions, for the coefficient of one variable in the two equations to be thesame, we multiply the first equation by 3.

If we do this, the coefficient of Y in the two equations will now be 3.

So that the correct option is
