2. Homework Review
# = 7(2p – 1) # (z + 3) = 4(z + 9)

3. Homework Review
# (x + 2) = 2(x + 2) # (d – 2) = 5(d + 8)

4. Homework Review
# n – 18 = 4(n + 2) # y + 5(y – 6) = 4

5. Homework Review
# z + 4 = 2(5z + 8) – # d – 12 = 4(d – 6)

When solving equations:
One Solution – This is when you end up with
“x = number”
Null Set (No Solutions) – This is when you end up with a statement that isn’t true “4 = 10”
Identity (Infinite Solutions) – This is when you end up with a statement that is always true. “2 = 2”
