Question

How do you solve `-x/7 + 4 ≥ 3x`?

Answer 1

`x <= 7`

Explanation:

Given `-x/7+4 >= 3x`

Simplify by multiplying everything by 7 (we don't like fractions)
`-x + 28 >= 3x`

Add `x` to both sides
`28 >= 4`

Divide both sides by `4`
`7 >= x`

Write the expression the other way around ('cause that's how most people like it)
`x <= 7`
