13x + 5 + 17x -4.5 + x explain why this is wrong show your 18x + 17x - 4.5 + x work 35x - 4.5 + x 30.5x + x 31.5x

The answerer is combining terms in x with constants

that is, 13x + 5 ≠ 18x

13x + 5 + 17x - 4.5 + x

= (13x + 17x + x ) + 5 - 4.5 ← collecting like terms

= 31x + 0.5 ← correct simplification
