Final answer:
To solve the equation 3x - 9x + 7 - 3 = -8, combine like terms to get -6x + 4 = -8, subtract 4 from both sides to get -6x = -12, and then divide by -6 to find x = 2.
Step-by-step explanation:
To solve the equation 3x - 9x + 7 - 3 = -8, let's simplify and solve step by step:
- Combine like terms for the variable x and constant terms on the left side: -6x + 4 = -8.
- Move the constant term on the left to the other side by subtracting 4 from both sides: -6x = -12.
- Finally, divide by the coefficient of x, which is -6 to isolate the variable: x = 2.
So the solution to the given equation is x = 2, which corresponds to the option 'c. O2' interpreted as 'c. 2' in the list of provided solutions.
