Solve for y:
3(y + 2) -16 = 8y

• y = -13/5
• y = -2
• y = 2
• y = -11/5

Solve for n:
6 - (8 - 4n) = 2(2n - 1)

• No solution
• n = 0
• All real solutions
• n = -2

Solve:
x = 2y - 4
5x - 3y = 1

• (-14, -5)
• (-14/13, 19/13)
• (-1, 3)
• (2, 3)

What are the two equations used when setting up this system:
Gavin is 6 more than 3 times as old as Dominic. If the sum of their ages is 58, how old is each?

• G = 6(3D)
  G + D = 58
• 3D = G + 6
  G + D = 58
• G = 6 + 3D
  G + D = 58
• D = 6 - 3G
  G + D = 58

What are the two equations used when setting up this system:
One number is 6 less than five times the second number. The sum of the numbers is 72. Find the numbers.

• x = 6 - 5y
  x + y = 72
• x = 5y - 6
  x + y = 72
• x = 6(5y)
  x + y = 72
• x - 6 = 5y
  x + y = 72

What are the two equations used when setting up this system:
The Lawn and Garden Shop sold 40 bags of lawn seed one week for a total of $263. Large bags of lawn seed sell for $8.50 and smaller bags for $5.75 each. How many bags of each size were sold?

• 8.5L + 5.75S = 263
  L + S = 40
• 8.5L + 5.75S = 40
  L + S = 263
• 8.5L = 5.75S
  L + S = 303
• 8.5L + 5.75S = 263
  8.5L + 5.75S = 40
