Answer:

4v - 7w = (101 , -36)

6u -8v = (-78 , 58)

2u +v - 4w = (40 , -4)

11u + 3w = (-88 , 89).

Step-by-step explanation:

u(-5, 7) ; v(6 , -2) ; w(-11,4)

4v - 7w = (4*6+[-7]*[-11] , 4*[-2] + [-7]*4)

=(24+77 , -6 - 28)

4v - 7w = (101 , -36)

6u - 8v = (6*[-5]+[-8]*6 , 6*7+[-8]*[-2] )

= (-30-48 , 42+16)

6u -8v = (-78 , 58)

2u + v - 4w = (-10+6+44 , 14 -2 -16)

2u +v - 4w = (40 , -4)

11u + 3w = (11*[-5]+3*[-11] , 7*11 +3*4)

= (-55-33 , 77+12)

11u + 3w = (-88 , 89)
