Respuesta :

The answer is true because, you must use the distribute then add both sides by 24 then divide both sides by -3 and then you will come up with your answer x=-1 which means that statement is true

Answer:

Yes, it's true. X=-1

Step-by-step explanation:

We have,

[tex]-3(x+8)=-21[/tex]

The objective is to discover which is the value of x, then first we need to divide both sides of the equation in -3,

[tex]\frac{-3(x-8)}{-3} =\frac{-21}{-3}[/tex]

Now we can simplify and the result is,

[tex]x+8=7[/tex]

Because [tex]\frac{-3(x+8)}{-3}=\frac{-3}{-3} (x+8)=x+8[/tex] and [tex]\frac{-21}{-3} =7[/tex]

Then we have to sum (-8) in both sides of the equation,

[tex]x+8+(-8)=7+(-8)[/tex]

And we have: [tex]x=-1[/tex]
