This is an easy problem with description being:

Given two integers, num and t. A number is achievable if it can become equal to num after applying the following operation:

Increase or decrease the number by 1, and simultaneously increase or decrease num by 1.

Return the maximum achievable number after applying the operation at most t times.

This problem is more of text interpretation than anything else. Basically you have a number and you have a number of operations (t). Every time an operation runs it increases or decreases number by 1.

Maximum achievable number would be the biggest number after all t operations (that increase/decrease by one).

To summarize, to solve this you need basically multiply the amount of operations by two (since there is two operations inside the main one) and sum with num.

class Solution {    public int theMaximumAchievableX(int num, int t) {        return num + 2 * t;    }}
