Final answer:

To find the unknown number, we solve the equation step by step. The final answer is 8.


Step-by-step explanation:

To find the unknown number, let's solve the equation step by step. We start by defining the unknown number as x. Multiplying x by 3 gives us 3x. Subtracting 6 from that gives us 3x - 6. Finally, adding 2 gives us 3x - 6 + 2, which simplifies to 3x - 4. We set this equal to 20, so 3x - 4 = 20. To isolate x, we can add 4 to both sides of the equation, giving us 3x = 24. Dividing both sides by 3 gives us x = 8. Therefore, the number is 8.
