Question : 3x + 2y + 2x = ?
Answer :
1) imagine, if X is Duck and Y is Bird
2) so we have 3 Duck, 2 Bird, and 2 Duck
3) search for the same category (Duck), and combine it ! 3x same like 2x > 3x + 2x
( Because 3x + 2x same like 3 Duck + 2 Duck )
4) combine X and Y, X and Y is defferent so ... separate x and y > 5x (from 3x + 2x) + 2y
3x + 2y + 2x = 5x + 2y
