10a.3 A 5.0-kg box is pulled by a horizontal force of 25 N and moves on a frictional floor. The coefficient of kinetic friction between the box and the floor is 0.20. An additional upward pulling force of 10 N is added to the box. What is the acceleration of the box? [Answer: 3.4 m/s²]

I have the answer, I just need a clear step by step explanation, please. Thank you.
