5x - 6y = - 54

• (-6, 4)

• (-8, 4)

• (8, 4)

• (6, 4)

Solve the system using matrices
x + 7y = - 21
9x + 7y = 35

• (7, -4)

• (-4, 7)

• (7, 4)

• (-4, -7)

Solving Systems:
Solve for x and y

• a

• b

• c

• d

Solve the linear systems together by using the values of b for two separate systems, then reducing an appropriate augmented matrix to reduced row echelon form. Write your answer as (x1, x2), (x1, x2) form.
