4 + (__)

Question

4 - 7+__

Answer 1

To solve the expressions, we can fill in the blank with the variable \( x \):

1. For the expression \( 4 + (__) \), we can just represent it as: \[ 4 + x \]

2. For the expression \( 4 - 7 + (__)\), we can similarly use: \[ 4 - 7 + x \]

If we want to simplify the second expression: \[ 4 - 7 + x = -3 + x \]

So, we end up with:

1. \( 4 + x \)
2. \( -3 + x \)

If you have a specific value for \( x \) or another condition, please provide that for a more specific solution!
