A __________ matrix is a matrix with rows = columns.

• Same

• Equal

• Big

• Square

Solve the system by matrix inverses

-5x + 5y = -10

-7x + 4y = 13

• (-7, -5)

• (-7, -9)

• (7, -9)

• (-7, 5)

Solve the system using matrix inverses

x + 2y = 2

5x - 6y = - 54

• (-6, 4)

• (-8, 4)

• (8, 4)

• (6, 4)

Use Matrix Inverses to solve the following:

-3x + y = 4

-5x + 2y - 4z = -3

-x - 4y - 6z = 11

• (2, -5, -3)

• (2, -4, -4)

• (2, -3, -5)

• (-3, -5, 2)

Use Matrix Inverses to Solve the Following:

2x - 5z = 6

-3x + 4y - 2z = 26

-3x + y - 4z = 18

• (-6, 5, -3)

• (5, -6, 4)

• (5, -6, -3)

• (-2, 4, -2)
