Final answer:
The value of x in the equation x-12=19 is found by adding 12 to both sides, which results in x being equal to 31.
Step-by-step explanation:
The student is asking for the value of x in the equation x-12=19. To solve for x, we need to isolate x on one side of the equation. This can be accomplished by adding 12 to both sides of the equation, as shown in the following steps:
- Add 12 to both sides of the equation: x - 12 + 12 = 19 + 12.
- Simplify both sides: x = 31.
Therefore, the value of x is 31.
