Answer 2

Let's solve the equation step by step:

1. Start by simplifying the expression inside the parentheses: (145 - (25 + x) / 3) - 2 = 30

2. Next, simplify the expression inside the innermost parentheses (25 + x) / 3: (145 - (25 + x) / 3) - 2 = 30 (145 - (25/3 + x/3)) - 2 = 30

3. Distribute the negative sign to both terms inside the inner parentheses: 145 - 25/3 - x/3 - 2 = 30

4. Combine like terms: 145 - (25/3 + 2) - x/3 = 30

5. Now, subtract (25/3 + 2) from 145: 145 - (25/3 + 2) - x/3 = 30 145 - (25/3 + 6/3) - x/3 = 30 145 - 31/3 - x/3 = 30

6. Move the constant terms to one side of the equation and the variable term to the other side: 145 - 31/3 - 30 = x/3

7. Combine the constants on the left side: 145 - 31/3 - 30 = x/3 (145 - 31/3 - 30) * 3 = x

8. Calculate the left side of the equation: (145 * 3 - 31 - 90) = x

9. Simplify the left side further: (435 - 31 - 90) = x

10. Continue to simplify: 435 - 31 - 90 = x

11. Subtract the numbers on the left side: 435 - 31 - 90 = x 404 - 90 = x

12. Finally, subtract: x = 314

So, the solution to the equation is x = 314.
