Find the scalars If possible, find scalars 
c1, c2, and c3, so that the following is true.
$$c_1(3, 2, -5) + c_2(-3, 3, 3) + c_3(-3, 8, 1) = (3, -3, 4)$$
I have no idea where to start. I think I have to make it into rref, but I am unsure. Can someone explain how to do this. Please. 

Its possibly the question is:$$c_1(3, 2, -5) + c_2(-3, 3, 3) + c_3(-3, 8, 1) = (3, -3, 4)$$
Then Solve the system of equations:
$$3c_1-3c_2-3c_3 =3, 2c_1+3c_2+8c_3 =-3,-5c_1+3c_2+c_3 =4.$$
