What is the value of u in the equation 5u – u + 3u = 14?

To solve the equation (5u – u + 3u = 14), follow these steps:

1. Combine the like terms on the left side:

[

(5u – u + 3u) = (5u + 3u – u) = 7u

]

2. The equation now looks like this:

[

7u = 14

]

3. To isolate (u), divide both sides by 7:

[

u = frac{14}{7} = 2

]

So, (u = 2). Great job working through it! If you need more help, feel free to ask or check the extended services page.
