Answer:

  see below

Step-by-step explanation:

Putting each equation in standard form is a good start.

1. Divide the first equation by 2. Divide the second equation by -5.

  • x +2y = 2
  • x - y = -1

2. Divide the first equation by 2; multiply the second by -1.

  • x +2y = 2
  • 3x -y = 1

3. Divide the first equation by 2.

  • x +2y = 2
  • 7x +5y = -1

4. Divide the first equation by 2.

  • x +2y = 2
  • 7x -y = 5

5. Divide the first equation by 2.

  • x +2y = 2
  • 7x -y = -1

JulijaS [17]

Answer:

5/12 left

Step-by-step explanation:

2- Once you have 3/12 and 8/12, add them to get 11/12.

3-Now you know you don't have a full pound. Then subtract 1/2 from 11/12 ->

11/12 - 6/12 = 5/12
