Answer:
Step-by-step explanation:
Let's revisit the equation and the solution using the values x = -4, 0, and 5.
The given equation is: 5 + x - 12 = x - 7
Let's go through the steps again to solve it:
5 + x - 12 = x - 7
Combine like terms:
x - 7 = x - 7
Now, subtract x from both sides:
x - x - 7 = x - x - 7
Simplify:
-7 = -7
The equation simplifies to -7 = -7, which is true.
Now, let's use the values x = -4, 0, and 5 to verify the solution.
For x = -4:
5 + (-4) - 12 = (-4) - 7
-11 = -11
The equation is satisfied for x = -4.
For x = 0:
5 + 0 - 12 = 0 - 7
-7 = -7
The equation is satisfied for x = 0.
For x = 5:
5 + 5 - 12 = 5 - 7
-2 = -2
The equation is satisfied for x = 5.
Therefore, the solution x = 0 is correct, and it satisfies the equation for the given values. My earlier statement that x = -4 and x = 5 do not satisfy the equation was incorrect. I apologize for the confusion caused.
