Solve the system. 7w + 7x + 7y + 7z = -7 2w + 2x + 2y + 5z = -1 w + 2x + y + 2z = 6 If the system has one solution, enter it below. If the system has infinitely many solutions, enter the solution for which the value of each arbitrary variable is set to 9. If the system has no solution, enter "N" for each variable. w= x= y= z=
Solve the system by using Gaussian elimination or Gauss-Jordan elimination. -- 5x+12y + 5z = -55 x-2y +3z = 14 -5x +3y – 2z = -22 The solution set is {000}:
Use the Gauss Jordan method to solve the system of equations if the system has infinitely many solutions, give the solution with z arbitrary. 2x - y + 5z = -3 x + 2y - 5z = 16 10y + 4z = 36
Suppose that a certain diet calls for 7 units of fat, 9 units of protein, and 16 units of carbohydrates for the main meal, and suppose that an individual has three possible foods to choose from to meet these requirements: • Food 1: Each ounce contains 2 units of fat, 2 units of protein, and 4 units of carbohydrates. • Food 2: Each ounce contains 3 units of fat, 1 unit of protein, and 2 units of carbohydrates. • Food...
In Exercises 5-14, use the addition method to solve each system of equations.

3. Use x = A-17 (you must) to solve the following system. It is known that the system has unique solution 2.0 + y + z = 4 10.x - 2y + 2z = -1 6.x - 2y + 4z = 8 (Answer: x = -1/2, y = 3/2 and 2 = 7/2)
(12 marks) Find all pairs (a, b) for which the following system has Exactly one solution Infinitely many solutions No solutions Solve the system whenever it is consistent. x + 2y + z = 3 ay + 5z = 10 2x + 7y + az = b
Help with all of this 1. The system of equations may have a unique solution, an infinite number of solutions, or no solution. Use matrices to find the general solution of the system, if a solution exists. (If there is no solution, enter NO SOLUTION. If there are infinitely many solutions, express your answers in terms of z as in Example 3.) 2x − 5y + z = 8 x + 4y − 6z = 4 3x − 4y −...
