Can a body be in motion, provided that the force acting on it is equal to the friction force?

According to 1 Newton’s law, if the resultant of all forces acting on the body is zero, then the body is at rest or moves uniformly and rectilinearly. Thus, if the force acting on the body is equal to the frictional force, and no other forces act on the body, the body can move uniformly in a straight line.
