Answer:
No solution or O
Step-by-step explanation:
Lets take this step by step. And assuming that you understand a bit of math I will go a bit faster and use stronger language! But Don´t worry, that does not mean it is hard!
(x+12)=(x+14)-3
We do not need to keep those parenthesis, because there is nothing to distribute! If we take those away, you can add common variables to each of the sides. Add 14 to -3 and you would get 11.
x+12=x+11
subtract the 11 on the right side with 12.
x+1=x
Subtract x with x and you get 0.
And 1 can not equal 0, so the question has no answer.
