Question

type the integer that makes the following subtraction sentence true:
$\square - -1 = 4$

Explanation:

Step1: Let the unknown integer be \( x \)

The equation is \( x - (-1) = 4 \)

Step2: Simplify the left side

We know that subtracting a negative is like adding the positive, so \( x + 1 = 4 \)

Step3: Solve for \( x \)

Subtract 1 from both sides: \( x = 4 - 1 \)
\( x = 3 \)
