Use the gauss-jordan method to solve the following system of equations x+y 7 3x+2y= 17 select the correct choice below and, if necessary, fill in the answer box to complete your choice. o a. the solution is (туре an ordered pair.) o b. there are infinitely many solutions. the solution is y, where y is any real number (use integers or fractions for any numbers in the expression.) o c. the system is inconsistent

The system has a unique solution

Step-by-step explanation:

We have the system of equations:

To solve this system for Gauss-Jordan method we need the augmented matrix, which is:

Next we need to transform the augmented matrix to the reduced row echelon form via elementary row operations as follows:

From the reduced row echelon form we have the solution of the system

b.-4 units

all you   do is count how many times you move

there is nothing below so i cannot
