Question

How do you solve `2\geq 8- 2k`?

Answer 1

`k>=3`

Explanation:

`color(blue)"Isolate" -2k` on the right side and collect numeric values on the left side.

subtract 8 from both sides.

`2-8>=cancel(8)cancel(-8)-2k`

`rArr-6>=-2k`

`"divide both sides by " -2`

[Remember to reverse the sign when dividing/multiplying by a negative quantity. ]

`(-6)/(-2)<=(cancel(-2) k )/cancel(-2)larrcolor(red)" reverse sign"`

`rArr3<=krArrk>=3" is the solution"`
