I'll do something similar to this, and I challenge you to do this on your own!
<something>-7=-34
Making that something equal to x, we have x-7=-34. Adding 7 to both sides using the addition property of equality (and to separate the x), we have
-34+7=x=-27
Good luck, and feel free to ask with any further questions!
Because pemdas helps you not get the process wrong
First you subtract three from three and -29 then you divide that by -2
It's being added by 2 each time
