Solve Systems of Equations by Elimination

Solve using Elimination Method:

4x+ 9y = 28

-4x -1y = -28

• (-7,0)

• (7,0)

• (6,7)

Solve using Elimination Method:

x - 1y = 11

2x + 1y = 19

• (10,-1)

• (3,-4)

• (6,7)

Solve the system:

1x + 6y = 17

-1x + 3y = -8

• (5, 2)

• (11, 1)

• no solution

Solve by elimination:

7x - 9y = 29

-7x - 2y = 15

• (-1.-4)

• (-1,4)

• (-1,6)

Solve using elimination.
