Question

6-2n is greater than or equal to one half n

Answer 1

6 - 2n >= 1/2n

1/2n <= 6-2n

1/2n+2n <= 6-2n+2n

2.5n <= 6

2.5 2.5

n<=2.4 or 2.4>=n

(6-2n is greater than or equal to one half n is the same as one half n less than or equal to 6-2n)

Explanation:

Answer 2

`n \leqslant 2.4`

Explanation:

`6 - 2n \geqslant (1)/(2) n`

Subtract 6 from both sides:.

`- 2n \geqslant (1)/(2) n - 6`

Subtract 1/2n from both sides:

`- 2 (1)/(2) n \geqslant 6`

`2 (1)/(2) n \leqslant 6`

Multiply 2 on both sides:

`5n \leqslant 12`

Divide both sides by 5

`n \leqslant 2.4`
