Suppose the following system of equations has a solution of (-7, 0), where A, B, C, D, E, and F are real numbers.
Ax + By = C
DX + Ey = F
Which systems are also guaranteed to have a solution of (-7, 0)? Select all that apply.
(-8 + A)X + (-8 + E)y = -8 + C
DX + By = F
Thing
(A + 2D)X + (B - 3E)y = C
(D + 2A)X + (E - 3B)y = F
AX + By = 0
(9A + D)X + (9B + E)y = 9C + F
(A - 2/0) x + (B - E) y = 6 - 2
DX + Ey = F
(A - 3D)X + (B + 3Ey = C + 3F
