To compare the solution of each question to 0, we need to solve each equation and determine whether the solution is less than 0, equal to 0, or greater than 0.
1) 9x - 8 = -8
Adding 8 to both sides, we have:
9x = 0
Dividing both sides by 9, we get:
x = 0
The solution, x = 0, is equal to 0.
2) -24 = 6 + -3x
Subtracting 6 from both sides, we have:
-30 = -3x
Dividing both sides by -3 (or multiplying both sides by -1/3), we get:
10 = x
The solution, x = 10, is greater than 0.
3) x/8 + 7 = -9
Subtracting 7 from both sides, we have:
x/8 = -16
Multiplying both sides by 8, we get:
x = -128
The solution, x = -128, is less than 0.

solve for x. 3x - 21 = 14 - 4x
To solve for x in the equation 3x - 21 = 14 - 4x, we will combine like terms and isolate the variable.
First, we can combine the x terms by adding 4x to both sides:
3x + 4x - 21 = 14 - 4x + 4x
This simplifies to:
7x - 21 = 14
Next, we can isolate the variable by adding 21 to both sides:
7x - 21 + 21 = 14 + 21
This simplifies to:
7x = 35
Finally, we solve for x by dividing both sides by 7:
(7x)/7 = 35/7
This simplifies to:
x = 5
Therefore, the solution to the equation is x = 5.
First, we can combine the x terms by adding 4x to both sides:
3x + 4x - 21 = 14 - 4x + 4x
This simplifies to:
7x - 21 = 14
Next, we can isolate the variable by adding 21 to both sides:
7x - 21 + 21 = 14 + 21
This simplifies to:
7x = 35
Finally, we solve for x by dividing both sides by 7:
(7x)/7 = 35/7
This simplifies to:
x = 5
Therefore, the solution to the equation is x = 5.
