Solving systems of equations by elimination

Solve the systems of equations by elimination

-4x -2y = - 12

4x + 8y = - 24

• x = 6

  y = 6

• x = 6

  y = - 6

• x = 6

  y = 4

• x = -6

  y = -6

Solve systems of equations by elimination

x - y = 11

2x + y = 19

• x = 1

  y = - 1

• x = 10

  y = - 10

• x = - 10

  y = - 1

• x = 10

  y = - 1
