To eliminate the variable y, one can multiply the first equation by the coefficient of y in the second equation and multiply the second equation by the coefficient of y in the first equation.
The coefficient of y in the first equation is 6, so we should multiply the second equation by 6.
Therefore, the second equation should be multiplied by 6 to eliminate the variable y.
So, the correct answer is 6.
