What is the value of u in the equation -3u – 16 = 17 if u = -11 or u = 9?

Let’s solve the equation step by step:

Given:

(-3u – 16 = 17)

1. Add 16 to both sides to isolate the term with (u):

(-3u – 16 + 16 = 17 + 16)

(-3u = 33)

2. Divide both sides by -3 to solve for (u):

(frac{-3u}{-3} = frac{33}{-3})

(u = -11)

So the correct answer is (u = -11). The other option (u = 9) is not a solution for the equation. Remember to check all steps when solving equations! If you need more in-depth assistance, feel free to check the extended services page.

To solve the equation -3u – 16 = 17, follow these steps:

1. Add 16 to both sides to isolate the term with u:

(-3u – 16 + 16 = 17 + 16)

This simplifies to:

(-3u = 33)

2. Divide both sides by -3 to solve for u:

(u = frac{33}{-3})

Thus,

(u = -11)

The correct answer is (u = -11).

So, the solution to the equation is (u = -11). If you have further questions or need more help understanding this concept, feel free to ask!
