(1 pt) Solve the system using elimination ± 4 x - 7 y = 20 9 x + 7 y = - 46 x = y = 2. (1 pt) Write the system 3 y - 7 z = 4 2 x - 6 y = - 3 10 x + 11 y - 4 z = - 5 in matrix form. x y z = 3. (1 pt) Write the augmented matrix of the system - 21 x + 67 z = 7 9 x + 9 y - z = - 6 93 x + 83 y = - 6 4. (1 pt) Solve the system using matrices (row operations) 2 x - 4 y + 5 z = 22 - 3 x - 6 y + 2 z = 41 2 x - 5 y - 2 z = - 3 x = y = z = 5. (1 pt) Solve the system x + y = - 5 4 x - 3 y = 43 11 x - 10 y = 134 x = y = 6. (1 pt) Solve the equation - 2 x - 9 y + 5 z = - 1 . x y z = + s + t . 7. (1 pt) Solve the system ± - 4 x 1 + x 2 = 3 - 8 x 1 + 2 x 2 = 6 ² x 1 x 2 ³ = ² ³ + ² ³ s . 8.
