To solve the equation -4x = 20, the goal is to isolate the variable x. To do this, you can start by dividing both sides of the equation by -4. This step helps to eliminate the coefficient of x.

When you divide the left side, -4x, by -4, you are left with x. On the right side, when you divide 20 by -4, the calculation is 20 ÷ -4, which equals -5.

Thus, the solution to the equation -4x = 20 is x = -5. This means that when x takes the value of -5, substituting it back into the original equation will satisfy it, confirming the solution is correct.
