Q: Solve the equation. Check your solution.

2 = 5y + 7
- y = 1 (incorrect)
- y = 5 (incorrect)
- y = 0 (incorrect)
- y = -1 (correct)
A: y = -1

Q: Solve the equation. Check your solution.

-8 = 20 - y
- y = -28 (There was a negative in front of the y.)
- y = 28 (Correct)
- y = 12 (You need to subtract 20 or add -20 to both sides.)
- y = -12 (You need to subtract 20 or add -20 to both sides.)
A: y = 28

Q: Solve the equation. Check your solution

-10 = 2 – 4r
- r = 3 (Correct)
- r = -3 (Incorrect. There is a negative on the 4r.)
- r = -2 (incorrect)
- r = 2 (incorrect)
A: r = 3

Q: Write the sentence as an equation. Use x to represent any unknown number.

Eight subtracted from ten times a number is 82.
- 10(x - 8) = 82 (incorrect)
- 8 - 10x = 82 (incorrect)
- 10x - 8 = 82 (correct)
- 8(10 - x) = 82 (incorrect)
A: 10x - 8 = 82

Q: Peter’s neighbor raises chickens; both hens and roosters. Their family sells the eggs, so they like to have four times as many hens as roosters. They currently have 45 birds.

Choose the equation that will help you solve for how many roosters, r, the neighbors have.
- 4r = 45 (4r is the number of hens. You need to add the number of roosters)
- r + 4r = 45
- r + r + 4 = 45
- 45 + 4r = 4
A: r + 4r = 45

Q: Peter’s neighbor raises chickens; both hens and roosters. Their family sells the eggs, so they like to have four times as many hens as roosters. They currently have 45 birds.
