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.
