Algebra 1 Chapter 5 Systems

Solve:

3x - y = 11

x + y = 5

• x = 4

  y = 1

• x = 4

  y = -1

• x = -4

  y = 1

• x = -4

  y = -1

Solve:

2x + 3y = 5

x + 3y = 7

• x = -2

  y = 3

• x = -2

  y = -3

• x = 2

  y = 3

• x = 2

  y = -3

Solve the following system of simultaneous equations:

4x + 5y + 10z = 42

2x + 3y = 18

  y=3

  z=1

• x=3

  y=4

  z=1

• x=1

  y=1

  z=1

• x=3

  y=3

  z=3
