To solve for the value of x in the equation -6x=48, you need to perform the same operation to both sides of the equation in order to keep the equation balanced.
In this case, the correct operation to perform is dividing both sides of the equation by -6. This will eliminate the -6 coefficient on the left side of the equation, isolating x.
So the answer is "divide by -6".
