Please help x - (-16) = - 12 x = ______

Illusion [34]

The first step for solving this expression is to know that when there is a "-" sign in front of the parenthesis,, then you must change the sign of each term in the parenthesis.
x + 16 = -12
Now move the constant to the right side and then change its sign.
x = -12 - 16
Lastly,, calculate the difference on the right side of the equation to find your final answer.
x = -28
Let me know if you have any further questions.
