5t   +  s/5  = 3

3t   +  6s   = 9           Multiply TOP equation by  -30  to get :

-150 t  -6s  = - 90      Now,   when you add the two bottom equations the 's' term will be gone and you can solve for 't'

                                      then use this value of 't' in any of the equations to calculate the value of 's'
