Question

How do you solve `-150- u > - 77`?

Answer 1

`u lt -73`

Explanation:

We have,

`color(white)(xxx) -150 - u gt -77`

`rArr cancel(-150) - u + cancel150 gt - 77 + 150` [Adding `150` to both sides]

`rArr -u gt 73`

`rArr u lt -73`

[When you multiply a negative number to both sides, the sign alters. (`gt` changes to `lt` and vice versa.)]

Hope this helps.
