Solve the problem.Three solutions of the equation Ax + By + Cz = 20 are given. Use a system of three equations in three variables to find the constants and write the equation.(8, -4, -10), (-8, 4, 20), (3, 8, 11.25)
A. A = 5; B = -5; C = 4; 5x - 5y + 4z = 20
B. A = 5; B = -5; C = 4; 5x + 4y - 5z = 20
C. A = 5; B = 5; C = -4; 5x + 5y - 4z = 20
D. A = 5; B = -5; C = 4; 5x + 4y + 5z = 20
