Question

Which value makes this equation true -4x = 20

Answer 1

`x=-5`

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:

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

This is the sane as:

`(-4x)/(-4)=(-5*-4)/(-4)`

We cancel out the common factors to get:

`x=-5`

Answer 2

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

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
