What is the solution to the following system? Solve using substitution (Write your answer as an ordered pair!)

2x - 3y = -1

y = x - 1

What is the solution to the following system? Solve using substitution (Write your answer as an ordered pair!)

x + 3y = 1

-3x - 3y = -15

What is the solution to the following system? Solve using Substitution

-3x + 3y = 4

-x + y = 3

What is the solution to the following system? Solve using elimination

3x - y = 3

x + y = 17

What is the solution to the following system? Solve using elimination

2x + 3y = 4

3x - 2y = 6

What is the solution to the following system? Solve using elimination

14x + 5y = 31

2x - 3y = -29
