To isolate x, we need to undo the operations in reverse order.
1. Start with the equation: 3x - 12 = 21.
2. Undo the subtraction by adding 12 to both sides: 3x - 12 + 12 = 21 + 12.
Simplifying, we get: 3x = 33.
3. Undo the multiplication by dividing both sides by 3: 3x / 3 = 33 / 3.
Simplifying, we get: x = 11.
Therefore, the solution is x = 11. So, the correct choice is B. x = 11.

To calculate the total cost including tax, we need to multiply the cost of the jeans by the tax rate and then add that to the original cost.
Tax = Cost of Jeans * Tax Rate
Tax = $45.99 * 7%
Tax = $45.99 * 0.07
Tax = $3.22
Total Cost = Cost of Jeans + Tax
Total Cost = $45.99 + $3.22
Total Cost = $49.21
Therefore, Hugo will have to pay a total of $49.21 for the jeans. Therefore, the correct choice is A. $49.21.
Tax = Cost of Jeans * Tax Rate
Tax = $45.99 * 7%
Tax = $45.99 * 0.07
Tax = $3.22
Total Cost = Cost of Jeans + Tax
Total Cost = $45.99 + $3.22
Total Cost = $49.21
Therefore, Hugo will have to pay a total of $49.21 for the jeans. Therefore, the correct choice is A. $49.21.
