Question

8 - 4z > -12 please explain steps

Answer 1

8 - 4z > -12

In questions like these, simply look at the greater than sign (>) as an equal sign.

8 - 4z > -12

Now, for equations like these, we're simply just trying to isolate "z", and in order to do this, we must subtract 8 from both sides.

-4z > -12 - 8

Simplify.

-4z > -20

Now, divide both sides by -4.

*Remember : when dividing by a negative number, you always switch the sign*

$\dfrac{-4\text{z}}{-4} > \dfrac{-20}{-4}$

Simplify.

z < 5

Answer 2

Answer:

→z < 5

Explanation:

→ 8 - 4z > -12

→ 8 - 4z > -12

→ -4z > -12 - 8

→ -4z > -20

Now, divide both sides by -4.

→ $\dfrac{-4\text{z}}{-4} > \dfrac{-20}{-4}$

Simplify,

→ z < 5
