Combine like terms and simplify expressions while preserving structure.
Translate term cards into a simplified expression
Problem
Term cards contain \(x\), \(x\), \(2x\), \(1\), and \(4\). Write their addition expression and combine like terms. Report the original sum followed by its simplified expression.
Big Picture
What this problem is really about
Write the five cards as an addition expression exactly as given before simplifying. Group the three variable cards and total their coefficients, remembering that the two-x card represents two copies, then add the constant cards separately. Report the original sum connected to its simplified form so both requested representations remain visible.
