Type the integer that makes the following addition sentence true:

+ 1 = –7

1 answer

To solve the equation \( x + 1 = -7 \), we need to isolate \( x \).

  1. Start with the equation: \[ x + 1 = -7 \]

  2. Subtract 1 from both sides: \[ x = -7 - 1 \]

  3. Simplify the right side: \[ x = -8 \]

Thus, the integer that makes the addition sentence true is \( \boxed{-8} \).
