Solving Systems Using Elimination Method

Solve the following system by using elimination:

3x - 5y = 8

2x + 5y = -3

• (1, 5)

• (1, -1)

• (-1, -1)

Solve the following system by using elimination:

-14x - 10y = -18

7x + 9y = -23

• (7, 8)

• (8, -7)

• (7, -8)

Solve the following system by using elimination:

-3x - 6y = -30

-7x + 8y = -4

• (4, 3)

• (3, 4)

• (4, -3)

Solve the following system by using elimination:

-3x - 6y = 24

4x + 4y = 4

• (-10, -9)

• (10, 9)

• (10, -9)

Solve the following system by using elimination:

-2x + 3y = 5

-5x + 2y = 29

• (-7, -3)

• (-7, 3)

• (7, -3)

Solve the following system by using elimination:

2x + 7y = -17

3x - 6y = -9

• (-5, 1)

• (-5, -1)

• (5, -1)

Solve the following system by using elimination:

-9x - 2y = -23

-10x - 5y = -20

• (-3, -2)

• (3, 2)

• (3, -2)

Solve the following system by using elimination:

3x + 3y = 0

7x + 5y = -16

• (8, 4)

• (-8, 8)

• (-8, -8)

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 with elimination?

4x + 3y = 1

x - 3y = -11

• cross out the 3y and -3y

• cross out the 4x and x

• change all the signs of the second equation

• add 1 and -11
