From the given condition above, travelling from the northernmost part to the southernmost part would mean that the cars traveled half of the circumference of the circle. With the given value for the circumference of the circular track, the car traveled 1.35 km.
x - y + 5z = 3 .... (1)
4x + z = 0
.......(2)
x + 3y + z = -9 .......(3)
From (2) z = -4x, Substitute for z in (1) and (3):-
x - y + 5(-4x) = 3
-19x + y = 3 ......(4)
x + 3y - 4x = -9
-3x + 3y = -9
- x + y = -3 .....(5)
Subtract:- (4) - (5) we get
-18x = 0
x = 0
So z = -4x = 0
Substituting for x and z in equation (3):-
3y = -9
y = -3
Answer is x = 0 , y = -3 and z = 0
