Step-by-step solution for: Solve Equations With Distributive Property Worksheet
Let's solve each expression step by step using the distributive property and then combine like terms. The distributive property states:
> $ a(b + c) = ab + ac $
We'll apply this to each problem, simplify, and combine like terms.

Distribute:
$ 3 \cdot 5n = 15n $, $ 3 \cdot 2 = 6 $ → $ 15n + 6 - 4n $
Combine like terms: $ (15n - 4n) + 6 = 11n + 6 $
✔ Answer: $ 11n + 6 $
---
Distribute:
$ 7 \cdot 4 = 28 $, $ 7 \cdot 2b = 14b $ → $ 8 + 28 + 14b $
Combine: $ 36 + 14b $
✔ Answer: $ 36 + 14b $
---
Distribute:
$ 2 \cdot 1 = 2 $, $ 2 \cdot (-9v) = -18v $ → $ 2 - 18v - 9v $
Combine: $ 2 - 27v $
✔ Answer: $ 2 - 27v $
---
Distribute:
$ -7 \cdot x = -7x $, $ -7 \cdot 7 = -49 $ → $ 8x - 7x - 49 $
Combine: $ x - 49 $
✔ Answer: $ x - 49 $
---
Distribute:
$ -8 \cdot 6 = -48 $, $ -8 \cdot (-7n) = +56n $ → $ -48 + 56n + 5n $
Combine: $ -48 + 61n $
✔ Answer: $ 61n - 48 $
---
Distribute:
$ -4 \cdot (-6a) = 24a $, $ -4 \cdot (-7) = 28 $ → $ 4 + 24a + 28 $

Distribute:
$ -4 \cdot (-20) = 80 $, $ -4 \cdot 7k = -28k $ → $ 80 - 28k $
$ 6 \cdot (-9) = -54 $, $ 6 \cdot (-k) = -6k $ → $ -54 - 6k $
Now combine: $ 80 - 28k - 54 - 6k = (80 - 54) + (-28k - 6k) = 26 - 34k $
✔ Answer: $ -34k + 26 $
