Answer:

You can't solve it.

Explanation:

In order to solve systems of equations in two variables, one of the equations cannot be the factor of the other. In the equations you gave, #2x+6y=48# is the double of #x+3y=24#. So we'd know #x+3y=48# even if the only equation we knew was #2x+6y=48#, because that's what you get when you divide it by #2#.

While solving a simultenaous set of two linear equations, you need distinct equations.
