Can someone solve or at least explain this

x=2

Step-by-step explanation:

i'm not sure how to do the modeling and the grouping part but here's the solve and check portion. I hope i helped a little!

solve;

3x=6 divide each side by 3 to isolate x

x=2

check;

plug 2 into x and see if the statement is true.

3(2)=6

6=6   true?  yes.

4th option is correct xy=-10
