Combine like terms and simplify expressions while preserving structure.
Combine variable terms and constants
Problem
Simplify the expression: \(4x~+~3~+~2x~+~5\)
Big Picture
What this problem is really about
Sort the expression into two like-term groups before calculating: terms carrying x belong together, while plain numbers belong together. Add the x-coefficients and the constants separately, then keep those two results apart because a variable term and a constant are unlike. This grouping prevents every visible number from being combined indiscriminately.
