Given the linear system 2.1"+3), - z =O x - 4)' +5z =0.(a ) Verify that Xl = I. Yl = - 1. Zl = - I is a solution.(b) Verify that X2 = - 2.)'2 = 2. Z2 = 2 is a solution.(e) Is x = X l + X2 = - I. Y = Yl + Y2 = I. andZ = Zl + Z2 = 1 a solution to the linear system?(d) Is 3x. 3y. 3z. where x. y. and; are as in part (c). asolution to the linear system?
