Given:

Equation: -6 + x = -12

Concept used:

To find the value of 'x' that satisfies the equation, we need to isolate 'x' on one side of the equation.

Calculation:

Starting with the equation:

-6 + x = -12

Add 6 to both sides:

x = -12 + 6

x = -6

Among the given options, the value of 'x' that satisfies the equation is indeed -6.

∴ The number that satisfies the equation −6 + x = −12 is -6.
