Use the system of equations below to answer the questions that follow. 2т -Зу %3 | 3.x +y = 5 (a) Write the augmented matrix for this system. (b) Perform the following row operations. In each new step, use you answer from the previous step. This is Gaussian elimination. i. Replace R1 with R1. ii. Replace R2 with -3R1 + R2. iii. Replace R2 with R2. Your answer should be in row-echelo: form. (c) Convert your transformed matrix back to a system of equations. Not that you now know half of the solution to the system. Substitute th value that you know into the first equation and solve for r. This i back substitution. (d) Look back at the matrix you wrote for (b) iii. Perform one more rov operation: replace R1 with 1.5R2 + R1. Your answer should be i reduced row-echelon form. This is Gauss-Jordan elimination. (e) You have solved the system two different ways. What is the solutio: to the system?

Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
Counting Theory
The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.

(a) Write the augmented matrix for this system.
(b) Perform the following row operations. In each new step, use your
answer from the previous step. This is Gaussian elimination.
i. Replace R1 with
R1.
ii. Replace R2 with -3R1 + R2.
iii. Replace R2 with

form.
(c) Convert your transformed matrix back to a system of equations. Note
that you now know half of the solution to the system. Substitute the
value that you know into the first equation and solve for r. This is
back substitution.
(d) Look back at the matrix you wrote for (b) iii. Perform one more row
operation: replace R1 with 1.5R2 + R1. Your answer should be in
reduced row-echelon form. This is Gauss-Jordan elimination.
(e) You have solved the system two different ways. What is the solution
to the system?
