Let's simplify the expression step by step:

The given expression is:

$11x - (-3x) + 43 - (-29) - 5x$

Step 1: Remove parentheses

• When subtracting a negative term, it becomes a positive: $11x + 3x + 43 + 29 - 5x$

Step 2: Combine like terms

• Combine the $x$-terms: $11x + 3x - 5x = 9x$
• Combine the constant terms: $43 + 29 = 72$

Final expression:

$9x + 72$

This is the simplified expression.
