About this illustration
A clean, flat illustration demonstrates the step-by-step process of evaluating an algebraic expression. It clearly shows how to evaluate '3x + 2' when 'x = 5' through four distinct, color-coded boxes connected by arrows. The steps are labeled 'Original expression' (3x + 2), 'Substitute x = 5' (3(5) + 2), 'Simplify multiplication' (15 + 2), and 'Final answer' (17). This instructional graphic is excellent for teaching fundamental algebra concepts in a clear, sequential manner, suitable for worksheets, slides, or as a classroom example in primary or middle school mathematics. There are no specific cultural or locale cues present.
