I need help with this

Consider the system of equations shown below. X - 4y = 14 3x - 12y = 42 -2x + 8y = -28 (a) Determine whether the nonhomogeneous system Ax = b is consistent. o consistent o inconsistent (b) If the system is consistent, then write the solution in the form x = X + x/, where x, is a particular solution of Ax = b and x/ is a solution of Ax = 0. (If the system is inconsistent, enter INCONSISTENT in both matrices.) x =
