Answer:
what's your question? I'm here to help if I can.
First way (no distribution)
-2(3z + 1) -10 = 4
-2(3z + 1) = 14
3z + 1 = -7
3z = -8
z = -8/3
Second way (with distribution)
-2(3z) - 2(1) - 10 = 4
-6z - 2 - 10 = 4
-6z = 16
z = 16/-6 = -8/3
z = 26/-6
Answer:
C
Step-by-step explanation:
So we have the expression:
To multiply, use the distributive property. Multiply (y+1) to each term on the left:
Distribute the variables:
Rearrange them to combine like terms:
The correct answer is C.
Edit: Typo
-2.6b + 4 = 0.9b - 17
<u>+2.6b </u> <u>+2.6b </u>
4 = 3.5b -17
<u> +17 </u> <u> +17 </u>
21 = 3.5b
6 = b
Answer: b = 6
