Write the system from the following statements

1. 1. Two numbers have the sum of 12 and the difference of 4

• x - y = 4

  x + y = 4

• x + y = 3

  x - y =4

• 4x + y = 12

  3x - y = 12

• x + y = 12

  x - y = 4

1. Write the system for the following statements:

2. 2. Two numbers have the sum of 13 and the difference of 3

• x + y = 3

  x - y = 13

• 3x + y = 1

  x - 13y = 3

• x + y = 13

  x - y = 3

• 2x + y = 13

  2x - y = 2

• x > 5

• x > 45

• x < -5

• x < -45
