Alg2 - Unit 3 - Lesson 6 - Solving Systems III

Solve the system of equations:
x + y + z = 4
x = -2y
z = -3y

• (2, -1, 3)
• (2, 3, 1)
• None of these
• (4, 1, -1)

Solve this system for x.
x + y + z = 21
y = 6
z = 5

• x = 10
• x = 11
• x = 20
• x = 32

Solve this system for x.
x + y + z = 30
y = 6 - z
z = 5

• x = 19
• x = 21
• x = 24
• x = 32

Solve the system of equations: 

• ( -2, 4, 3)
• ( 2, 1, 6)
• No solution
• None of these
