Find x, y, x. If 50x+10y+z = 50000. And x+y+z = 5000. Please send me this question's answer.

To find out unique solution number of variables should be equal to number of equations, for this you can first subtract the equation z will elimiate and then you will get an equation with two variables then you can assume y as k and then u can find out value of x in terms of k.
