Answer: The solution to the equation is x = -4.
Step-by-step explanation: Let's start by simplifying the left side of the equation:
8 + 9 = 17
Now let's simplify the right side of the equation:
3x - 13 + 10 + 10 + 10 + 12 = 3x + 29
Now that we have simplified both sides, we can set them equal to each other:
17 = 3x + 29
Next, let's isolate the variable "x" by moving the constants to the other side of the equation:
17 - 29 = 3x
-12 = 3x
To solve for "x", we divide both sides of the equation by 3:
-12/3 = 3x/3
-4 = x
Therefore, the solution to the equation is x = -4.
