Question

what is the value?$8 + 4x \geqslant 12$

Answer 1

Given the equation:

$8\text{ }+\text{ 4x }\ge\text{ 12}$

We are required to find x.

First subtract 8 from both sides:

$8\text{ - 8 }+\text{ 4x }\ge\text{ 12 -8}$$4x\text{ }\ge\text{ 4}$

Now, divide both sides by 4

$\frac{4x}{4}\text{ }\ge\text{ }\frac{4}{4}$$x\text{ }\ge\text{ 1}$

We did not flip the inequality sign because we divided both sides by a posite number and not a negative number. The inequality sign should be flipped only when both sides are divided by a negative number.
