Sure! Let’s simplify each of the 10 algebraic expressions step by step. The main technique we’ll use is the
Distributive Property:
>
a(b + c) = ab + ac
and then combine
like terms if needed.

1) -3(9 + 6w) + 8
Step 1: Distribute -3 to both terms inside the parentheses:
= (-3)(9) + (-3)(6w) + 8
= -27 - 18w + 8
Step 2: Combine like terms (-27 and +8):
= -18w - 19
✔ Final Answer: -18w - 19
---
2) 4(-5y - 9)
Step 1: Distribute 4 to both terms:
= (4)(-5y) + (4)(-9)
= -20y - 36
✔ Final Answer: -20y - 36
---
3) 9(-5 + 3c)
Step 1: Distribute 9:
= (9)(-5) + (9)(3c)
= -45 + 27c
Step 2: Rearrange (optional, but standard form puts variable first):
= 27c - 45
✔ Final Answer: 27c - 45
---
4) -3(6 - 5r)
Step 1: Distribute -3:
= (-3)(6) + (-3)(-5r)
= -18 + 15r
Step 2: Rearrange:
= 15r - 18
✔ Final Answer: 15r - 18
---
5) 8(-9p - 2) + 7
Step 1: Distribute 8:
= (8)(-9p) + (8)(-2) + 7
= -72p - 16 + 7
Step 2: Combine constants:
= -72p - 9
✔ Final Answer: -72p - 9
---
6) 2(-4 + 8h)
Step 1: Distribute 2:
= (2)(-4) + (2)(8h)
= -8 + 16h
Step 2: Rearrange:
= 16h - 8
✔ Final Answer: 16h - 8
---
7) -8(-3 + 6w) - 7w
Step 1: Distribute -8:
= (-8)(-3) + (-8)(6w) - 7w
= 24 - 48w - 7w
Step 2: Combine like terms (-48w - 7w):
= 24 - 55w
Step 3: Rearrange:
= -55w + 24
✔ Final Answer: -55w + 24
---
8) 7(-9r - 5)
Step 1: Distribute 7:
= (7)(-9r) + (7)(-5)
= -63r - 35
✔ Final Answer: -63r - 35
---
9) -6s - 7(2 + 9s)
Step 1: Distribute -7:
= -6s - [7×2 + 7×9s]
= -6s - (14 + 63s)
Step 2: Distribute the negative sign:
= -6s - 14 - 63s
Step 3: Combine like terms (-6s - 63s):
= -69s - 14
✔ Final Answer: -69s - 14
---
10) -6 + 4(-9y + 8)
Step 1: Distribute 4:
= -6 + [4×(-9y) + 4×8]
= -6 + (-36y + 32)
Step 2: Remove brackets and rearrange:
= -36y -6 + 32
Step 3: Combine constants:
= -36y + 26
✔ Final Answer: -36y + 26
