Question 2 of 10 Use the matrix tool to solve the system of equations. Choose the correct
ordered pair.
4x + 5y = 2
5x - 3y = 21

(3 , -2)

Step-by-step explanation:

4   5   2                        5  -3   21                      1  -8   19  -> * -4

5  -3    21  -> switch     4   5   2   -> * -1   ->      4   5   2              ->

1    -8    19                  -> 1     0     3                          1     0     3

0  37   -74   -> *8/37      0  37   -74   -> * 1/37   ->   0    1     -2
