I am sorry if it is wrong topic , and sorry if it is a bit bad text - translated it from estonian to english. If someone could do it and maybe explain this- that would be great.

1. The problem statement, all variables and given/known data

1)In the reference system K is point M with coordinates x=5m , y=2m and z=8m. You have to find that point coordinates in refenrece system K', which moves with velocity 7 m/s aiming z-axis.

2)Particles equations of motion in reference system K' is
x'=5t+4
y'=0
z'=0

Write out this particles equations of motion in reference system K, if:

a) K' is still according to K and its deperature point coordinates are O' (2;0;0).

b) K' is moving according to K evenly and straight with velocity 10 m/s aiming x-axis.
On observation start-moment t=0 both coordinate systems deperature points were same.

2. Relevant equations
Galilei's principle of relativity, Galilean transformation and and inertial reference frame.

3. The attempt at a solution

Hi latel, welcome to PF!

We don't do your homework for you here; you need to make an attempt and show your work, so that we can see where you are having trouble.
