Systems of Equations

Steffen graphed two lines in order to find the solution to a given system of equations.
What is the solution?

• (-3,-8)
• (-8,-3)
• (3,-8)
• (8,3)

Solve for x and y
3x + 2y = 16
7x + y = 19

• (-2,5)
• (-2,-5)
• (2,-5)
• (2,5)

Solve the system
2x + 3y = 12
5x - y = 13

• x = -3, y = -2
• x = 1.5, y = 2
• x = 6, y = 0
• x = 3, y = 2

Solve the system of equations by elimination.
-x + y = -13
-8x - 4y = -8 

• (5, 8)
• (5, -8)
• (-5, -18)
• (-5, 8)

Solve for x and y
3x + 2y = 16
7x + y = 19

• (-2,5)
• (-2,-5)
• (2,-5)
• (2,5)

x-4y = 16
5x + 4y = 8

• (4,-3)
• (-3,4)
• (4,3)
• (3,-4)

5x - 4y  =-16
x+ 2y = -6

• (-4,-1)
• (5,-1)
• (-5,-1)
• (4,1)

Solve the system of equations: 

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

Solve the system of equations: 

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

Solve the system of equations: 

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