Use elimination to solve each system of equations, if possible. Identify the system as consistent or inconsistent. If the system is consistent, state whether the equations are dependent or independent. -0.5x - 0.5y = 1.50.3x - 0.2y = -2.4
A. inconsistent B. (-6, 3); consistent and independent C. (-2.7, 7.5); consistent and independent D. (-6.6, 5.3); consistent and independent
