For the equation, we only know that x+3 = 12 or x+3 = - 12.

(X+3=12) First possible solution.

X + 3 = 12

Add - 3 to each side which will get rid of 3 and leave X = 12-3

Which leads to X = 9.

(X+3 = - 12) Second possible solution.

X+3 = - 12

Add - 3 to both sides which will get rid of 3 and leave x = - 12 - 3

Which leads to x = - 15

Answer: x = 9 or x = - 15
