Question

Is either x=5 or x=6 a solution to 4x>21

Answer 1

x=6

Explanation:

The inequality is saying that 4×x is more than 21

4×5 = 20 which is not more than 21

4×6 = 24 which is more than 21

Therefore the lowest integer solution to this is that x = 6

Answer 2

`4x > 21`

`\cfrac{4x}{4} > \cfrac{21}{4}`

`x > \cfrac{21}{4}`

I'd say no!
