Start with the given equation: \(x - (-5) = 12\).
Recall that subtracting a negative number is the same as adding its positive counterpart, so rewrite the equation as: \(x + 5 = 12\).
To isolate \(x\), use the subtraction property of equality by subtracting 5 from both sides: \(x + 5 - 5 = 12 - 5\).
Simplify both sides: \(x = 12 - 5\).
The equation is now solved for \(x\), and you can find the value by performing the subtraction on the right side.
