The image represents two equations that have come from which worded problem?:

• Find two numbers whose sum is 10 and whose difference is 4.

• Find two numbers that equal 7 and when divided equal 3.

• Find two numbers whose difference is 10 and whose sum is 4.

• Find three numbers whose sum is 4 and difference is 10.

3x - y = 11

x + y = 5

• x = 4

  y = 1

• x = 4

  y = -1

• x = -4

  y = 1

• x = -4

  y = -1

Solve:

3x + 5y = 4

4x - 5y = -18

• x = -2

  y = 2

• x = -2

  y = -2

• x = 2

  y = -2

• x = 2

  y = 2

Solve:

2x + 3y = 5

x + 3y = 7

• x = -2

  y = 3

• x = -2

  y = -3

• x = 2

  y = 3

• x = 2

  y = -3

Solve:

2x + 5y = 29

x + 5y = 22

• x = 7

  y = 3

• x = -7

  y = -3

• x = 7

  y = -3

• x = -7

  y = 3
