x - 3 = -27
You have to get x by itself. So, you do the opposite of subtraction which is addition.
x -3 + 3 = -27 + 3
Answer: x = -24
Note: 27 is negative and 3 is positive. So, you subtract. Be careful, watch the signs!!!
Check answer:
Put -24 in place of x in the problem.
-24 - 3 = -27
24 and 3 are both negative. So, you add.
Note: A minus sign in front of a positive number makes that number negative.
-24 + -3 = -27
-27 = -27

If your answer is x = -30, then put -30 in place of x in the problem.
-30 - 3 = -27
30 and 3 are both negative. A minus sign in front of a positive number makes that number negative. You have to add both negative numbers.
-30 + -3 = -27
-33 = -27
Your answer doesn't equal -27.
