Question

Solve the inequality for u.
22≤-4u-2
Simplify your answer as much as possible.

Answer 1

u ≤ -6

Explanation:

Given :

• 22 ≤ -4u - 2

Add 2 on both sides :

• 22 + 2 ≤ -4u - 2 + 2
• -4u ≥ 24

Divide both sides by -4 (remember the sign changes direction when divided by a negative number) :

• -4u/-4 ≥ 24/-4
• u ≤ -6

Solve the inequality for u:-

22≤-4u-2.

`\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}`

First, let's add 2 on both sides:-

`\longmapsto\sf{24\geq -4u}`

Switching the order (and flipping the inequality sign):-

`\longmapsto\sf{-4u\geq 24}`

Divide by -4 on both sides:-

`\longmapsto\sf{u\leq 6}`

`\bigstar` Notice that the inequality sign changed from "less than" to "greater than". This happened because we divided by a negative number on both sides.

• Henceforth, We conclude that:-

`\longmapsto\underline{\boxed{\sf{u\leq -6}}}`

Good luck with your studies.
