Close, why did you switch the direction of the sign?

annie12m · Answer

idk i just thought you had to, i remembered learning something that you had to switch the sign for some reason but forgot the reason

michele_laino · Answer

hint:
if I subtract 6 to both sides, I get:
$$2x + 6 - 6 \geqslant  - 4 - 6$$

study312 · Answer

So what is -4 - 6?

annie12m · Answer

-4 - 6 = -4 + -6 = -10

study312 · Answer

good now you have 2x ≥ -10 so do you know what to do next?

michele_laino · Answer

correct! so I can rewrite the original inequality as below:
$$2x \geqslant  - 10$$

annie12m · Answer

2x/2 
-10/2 = -5

study312 · Answer

Yes! just divided 2 from both sides and now we have x ≥ -5
