Answer: I can't find the answer :(
Step-by-step explanation: :(
It would be: 0.25 = 25/100 = 1/4
so, your answer is 1/4
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
3x2+8x-10 // the answer is 8x
