Using elimination method, the solution of the system of equation is (-9, 15)
3s + 2t = 3
s + 1 / 3 t = - 4
multiply equation(ii) by 3
3s + 2t = 3
3s + t = - 12
subtract equation(ii) from equation(i)
2t -t = 3 - (-12)
t = 3 + 12
t = 15
Therefore,
3s + 2t = 3
3s + 2(15) = 3
3s + 30 = 3
3s = 3 - 30
3s = - 27
s = -27 / 3
s = -9
