Which equation has solution x = -3? https://gyazo.com/eff6d49afd3b20a1d4c5606fdabc17ce

OpenStudy (melissa_something):

The answer is D. Do you know how? :)

OpenStudy (jamaljunior):

no. explain pls

OpenStudy (melissa_something):

Well you'll divide both sides by 1/2 to get rid of it, so -6 · 2 will give you -12

OpenStudy (melissa_something):

It will give you 2x-6=12

OpenStudy (melissa_something):

That looks more simple, right? Got it from there?

OpenStudy (jamaljunior):

yes. ty @Melissa_Something
