Finding Solution to the Equation

Identify the solution to this system of equations.

• (4, -1)

• (-1, 4)

• (-4, 1)

• (-4, -1)

Solve  the system of equations.  
   x + 5y = -27
-2x - 5y = 24

• (3, 6)

• (-3, -6)

• (-3, -4)

• (3, -6)

Solve by elimination: 7x+y=-9 -3x-y=5

• No solution

• (1,8)

• (-1,-3)

• (-1,-2)

Solve by elimination

-6x + 5y = 1

6x + 4y = -10

• (-1,7/5)

• (0,-1)

• (1,1)

• (-1,-1)

Solve by elimination:
-9x - 4y = -20
5x + 4y = 4

• (-4,4)

• (4,4)

• (4,-4)

• (-4,-4)

Solve by elimination:

7x + y = -9

-3x - y = 5

• No solution

• (1,8)

• (-1,-3)

• (-1,-2)

What would be the first step in finding the solution using elimination?

2x + 2y = -2

3x - 2y = 12

• you cannot solve this using eliminiation

• cross out the 2x and 3x

• cross out the 2y and -2y

• change to slope intercept form and graph

solve the system of equation using elimination

x - 2y = -19

5x + 2y = 1

• (3, -8)

• (-3, 11)

• (1, 0)

• (-3,8)

7x - y = 10

-7x + y = -14

• No Solution

• (4, 1)

• Infinitely Many Solutions

• (2, -4)

Solve using Elimination Method:

x - y = 11

2x + y = 19

• (10,-1)

• (-1,10)

• (3,-4)

• (6,7)
