To solve this problem, we first need to set up an equation. Let's represent the unknown number as "x." The equation would be 3x - 11 = 10. To find the value of x, we would first add 11 to both sides to isolate the term with x, giving us 3x = 21. Finally, we would divide both sides by 3 to find that the number is x = 7.
