Solving Systems (Lesson 7 & 8)

What is the solution to this system of equations?

• (4, -1)
• (-1, 4)
• (-4, 1)
• (-4, -1)

Solve the system of equations.
x + 2y = -3
x - y = -12

• (-9, 3)
• (-7 ,5)
• (3, 15)
• (-9, 6)

Solve by Substitution:

x = -3y - 17

2x + 3y = -7

• (1, -20)

• (3, 0)

• (-5, -9)

• (10 , -9)

Solve the system:
3x + y = 19
2x - y = 6

• (5, 14)
• (4, 5)
• (5, 4)
• (14, 5)

Solve the following system by graphing.  What is the solution?

• Infinite number of solutions
• (3, 3)
• (3, -3)
• (-3, 3)

Solve the system:
x + 6y = 17
x - 3y = 8

• (5, 2)
• (11, 1)
• (1, 11)
• no solution

• x = -128

• x = 14

• x = -14

• x = 15 

solve the system

• No solution

• infinite solutions

• (0,0)

• (5,1)

• (5,0)

Solve the system by elimination.
  5x + 8y = -12
3x + 5y = -7

• (1, -10)
• No solution
• (-4, 1)
• (1, 10)
