Answer :
Final answer:
The value of X that makes the equation X + 7 = -9 true is -16. This is sorted by subtracting 7 from both sides of the equation which gives X = -16.
Explanation:
The subject of this question is Mathematics and it's suited for a Middle School grade. The equation given in the question is X + 7 = -9. The student is asked to find the value of X that makes this equation true. The correct way to solve this equation is to subtract 7 from both sides of the equation which gives you X = -9 - 7, thus, the correct solution for the equation X + 7 = -9 is X = -16.
The proposed answers are 1) -16 2) -2 3) 0 4) 2 5) 16, From these options, the correct value of X is -16, which corresponds to the first option. Remember when dealing with equations, it's important to always maintain the balance, whatever you do to one side of the equation must be done to the other side as well.
