∙ 13y agoDivision by 4:
4x ≤ 12
divide both sides by 4:
x ≤ 3

The direction of the inequality is reversed. Note that the if the inequality included "or equals" before, then it will after. 4 < 5 multiplied by -1 gives -4 > -5 5 >= 4 multiplied by -1 gives -5 <= -4

The area in the inequality gives you choices. Like the number of pounds that an elevator can carry is anything less than its maximum.
3x ≥ 12. Dividing both sides by 3 gives x ≥ 4
An inequality requires an inequality sign, usually "less than", "less-than-or-equal", "greater than", or "greater than or equal". Assuming one of these inequality signs is between the "4x" and the "12", for example: 4x < 12, just divide both sides by 4. Just as when you solve equations, the idea is to isolate the variable on one side.
A substance with equal numbers of H+ and OH- ions is a neutral solution, not alkaline. Alkaline solutions have higher concentrations of OH- ions, making them basic.
