Answer:

x = -5

Explanation:

We are required to solve for x in the given equation:


-4x=20

In order to solve for x, first, determine the coefficient of x.

The coefficient of x is the number beside x.

• Thus, the coefficient of x = -4.

Divide both sides of the equation by -4.


\begin{gathered} (-4x)/(-4)=(20)/(-4) \\ x=(4*5)/(-4) \end{gathered}

Cancel out the common term in the numerator and denominator.


\begin{gathered} x=\frac{\cancel{4}*-5}{\cancel{4}} \\ x=-5 \end{gathered}

The value of x is -5.
