Executive Functioning - Working Memory:

When solving the bottom equation- which step do you take to solve for y?

• add x on both sides, utilizing the same operation

• add y on both sides, utilizing the same operation

• subtract x on both sides, using inverse operations

• subtract y on both sides, using inverse operations

Where would you plug in y = 1 - x into the first equation 3x + 7y = 6?

• Plug the expression in for x, right next to the 3

• Plug the expression in for y, right next to the 7

• common
• different
• positive
• negative

It is VERY IMPORTANT that you write down your work. You will need the equations that you write for future problems. Please select which option best fits your understanding of the previous statement.

(Select all that apply)

• I understand and will write down ALL of my work

• I understand I will need the equations later on

Part A

Which equation is one of the two equations needed to represent the model?

• 2x + 6y = 1

• 6x + 2y = 1

• 2x + 6y = 5

• 6x + 2y = 5

Part B

Which equation is the other equation needed to represent the model?

• x + y = 5

• x + y = 1

• x + y = 60

• 2x + 6y = 60

Part C
