What is the solution to the system?

• (0, 3)

• (1, -1)

• (-3, 1)

• (1, 3)

Solve for x

Hint: Solve using Elimination Method:

• 1/2

• 1

• -1

• -1/2

Which operation would allow elimination by either addition or subtraction? (check all that apply---take your time!)

• Double the bottom row

• Divide the top row by 2

• Multiply the bottom row by 4

• Multiply the top row by 4

• Multiply the top row by 2 and the bottom row by 4

What is the solution to the system?

• (0, 3)

• (1, -1)

• (-3, 1)

• (1, 3)

Using elimination method, what would the correct next step be? Not interested in the answer.

• 3x = -3

• x - 6y = -24

• x = -3

• 3x = 3

Solve the following system of equations using the elimination method:

• (-2, 1)

• no solutions

• (-2, 0)

• (-1, -3)

What is the best first step to solve this system by elimination?

• Add the equations to eliminate y

• Subtract the equations to eliminate y

• Multiply the second equation by 3.

• Multiply the first equation by 2

solve using elimination

• (0,2)

• (1,3)

• (0,3)

• (2,1)
