Solve the system by using the substitution method:

2x − 3y = −1

y = x − 1

• (-2,-3)

• (0,-1)

• (3,4)

• (4,3)

Solve the system by using the substitution method:

y = 2x -11

-3y = -6x -15

• (-1.5,-4)

• (1.5,4)

• No solution (parallel lines)

• Infinitely many solutions

Solve the system by using the substitution method:

y = 4x+1

3x + 2y = 13

• (1, 5)

• (5, 1)

• (0.25, 2)

• ∅

Solve the system by using the elimination method:

3x + 2y = 16

7x + y = 19

• (-2,5)

• (-2,-5)

• (2,-5)

• (2,5)
