Question

How do you solve `a/5> 10`?

Answer 1

`a > 50`

Explanation:

One of the permitted operations for inequalities (that doesn't effect the validity or orientation of the inequality) is multiplication of both sides by the same constant provided that constant is greater than zero.

Multiplying both sides of `color(blue)(a/5 > 10)` by `color(blue)(5)` gives:
`color(white)("XXX")color(blue)(a > 50)`
