Solve the system using substitution:

x + y = 19

y = 3x - 1

• (14, 5)

• (11, 8)

• (5, 14)

• (8, 11)

What is the solution to the system?

• (0, 3)
• (1, -1)
• (-3, 1)
• (1, 3)

When does a system of equations have no solutions?

• When the lines cross
• When slopes of the lines are different
• When the slopes are the same
• There is ALWAYS a solution sir!

Solve the system using elimination:
