Question

which value makes this equation true -4x = 20

Answer 1

Answer:

x= -5 makes the given equation  -4x = 20 true

Step-by-step explanation:

We have been given the equation;

-4x = 20

we are to determine the value of x that will make the equation true. We simply make x the subject of the formula;

divide both sides of the equation by -4;

(-4x)/(-4) = 20/(-4)

x = -5

Therefore, x= -5 makes the given equation  -4x = 20 true

Answer 2

Answer:

$x=-5$

Step-by-step explanation:

The given linear equation is:

-4x = 20

To find the value of x that makes the equation true, we need to solve for x.

We divide both sides by -4 to obtain:

$\frac{-4x}{-4}=\frac{20}{-4}$

This is the sane as:

$\frac{-4x}{-4}=\frac{-5\times-4}{-4}$

We cancel out the common factors to get:

$x=-5$
