How do you solve #u/5 + u/10 - u/6 = 1#?

Answer 1

#u=15/2 or 7.5#

We can solve this by putting everything on the left side on a common denominator. If you need me to explain how to do this, feel free to say so

#u/5+u/10-u/6=1# #(6u)/30+(3u)/30-(5u)/30=1# #(4u)/30=1#

Now that we have this, its a matter of multiplying and dividing to get #u# by itself on one side:

#4u=30# #u=30/4# #u=15/2 or 7.5#

To solve the equation u/5 + u/10 - u/6 = 1, you can follow these steps:

Find a common denominator for the fractions, which is 30.
Multiply both sides of the equation by 30 to eliminate the fractions.
Simplify the equation and solve for u.
The solution to the equation is u = 30.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
