Answer 2

You have the variable b on both sides. You also have numbers, -1 and 4, on both sides.

Answer 3

Step 1. Subtract 24 from both sides: 8b−1−24b=24b+4−24b
= −16b−1=4

Answer 4

If I subtract \(4\) from both sides, I get:
\[8b - 1 - 4 = 24b + 4 - 4\]
please simplify

Answer 5

You need all variables on one side, and all numbers on the other side.

Answer 6

Step 2. Add 1 to both sides: −16b−1+1=4+1
−16b=5

Answer 7

since \(-1-4=-5\) and \(4-4=0\) then i can write:
\[8b - 5 = 24b\]

Answer 8

8b-1=24b+4
8b-24b-1=4
-16b-1=4
-16b=4+1
-16b=5
b=5/-16
b=-5/16
Answer: -5/16

Answer 9

-0.3125

Answer 10

correct! @freemap it is \(b=-5/16=-0.3125\)

Answer 11

That's why, -5/16=-0.3125, they're the same.

Answer 12

Thanks to everyone that helped towards this Question

Answer 13

\(8b-1 = 24b + 4\)

Step 1. Add 1 to both sides:

\(8b - 1 \color{red}{+ 1} = 24b + 4 \color{red}{+ 1}\)

\(8b = 24b + 5\)

Step 2. subtract 24b from both sides:

\(8b \color{red}{- 24b} = 24b \color{red}{- 24b} + 5\)

\(-16b = 5\)

Step 3. Divide both sides by -16:

\(\dfrac{-16b}{\color{red}{-16}} = \dfrac{5}{\color{red}{-16}} \)

\(b = -\dfrac{5}{16} \)

Answer 14

Thanks for the illustration

Answer 15

By the way, can anyone help me with a differential equations problem? http://openstudy.com/study#/updates/562540b9e4b042c91fffc8a3

Answer 16

I would but I'm not good at math, so sorry.
