Solving a System of Equations

Solve for x and y
y = 2x + 1
y = 4x - 1

• (1,3)
• (-1,-3)
• (-1,3)
• (3,1)

Solve:
y=8x+1
y=6x+3

• (1, 9)
• (4, 14)
• (0, 1)
• (2, 4)

Solve for x and y
5x + 3y = 7
y = 4

• (4,1)
• (4,-1)
• (1,4)
• (-1,4)

4x - 2y = 7
 x + 2y = 3
What are x and y?

• x = 2, y = 2
• x = 1/2, y = 2
• x = 2, y = 1/2
• x = 2, y = -2

Give the solution to the system

• (3,1)
• (1,3)
• (-1,3)
• No solution

6x + y = -1

3x + y = - 4

• (3, 1)

• (1, 7)

• (-3, 1)

• (1, -7)

Solve the system given:
3x - y = 7
2x + y = 3

• (-1,2)
• (5,4)
• (4,5)
• (2,-1)

3x - 2y = 14

2x + 2y = 6,

Solve the system.

• x = 1, y = 2

• x = 2, y = 1

• x = -4, y = 1

• x = 4, y = -1

^{What is the solution?} 

• 1
• -2
• (1, 2)
• (1, -1)

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

• (-2,5)
