Solve the problem.Three solutions of the equation Ax + By + Cz = 4 are given. Use a system of three equations in three variables to find the constants and write the equation.(-7, 6, -51), (7, -6, 47), (5, -7, 42.5)
A. A = 8; B = 7; C = 2; 8x + 7y + 2z = 4 B. A = 8; B = -7; C = -2; 8x - 2y + 7z = 4 C. A = 8; B = -7; C = -2; 8x - 7y - 2z = 4 D. A = 8; B = -7; C = -2; 8x - 2y - 7z = 4
