The system Px = Qy = R and Tx + Uy =V has the solution (2,9), where P, Q, R, T, U and V are not = to 0. Select all systems of equations that have the same solution.
a. Px + Qy = R
(P + T)x + (Q + U)y = R + V
b. Px + Qy = R
(P +2T)x +Q + 2U)y = R- 2V
c. (T - P)x = (U - Q)y = V - R
Tx + Uy = V
d (T - P)x +(Q + U)y = V - R
Tx + Uy = V
