please help! I need to solve it algebraically and if you can show your work/explain how you got the answer that would help a ton because I need that to!

The answer is x=-10
Step-by-step explanation:
the reasoning is you do the inverse or opposite of three to both sides so you add +3 to both sides so the -3 and the +3 would cancel out then you would add +3 to the integer -23 and get -20 next is you divide by 2 on each side so you 2÷2 which would cancel out and then -20÷2 which would equal -10
Hence the answer is x=-10
