One term was increased by 19. How should the second term be changed so that the sum does not change?

Mathematical action with terms is “addition”.

Let’s take an example:

1 + 2 = 3;

The terms are two numbers that are added to each other. As a result, their sum is obtained. On the letter, the terms appear before and after the “+” sign, and the sum – after the “=” sign behind them.
Here number 1 is the first term or “left” term, and number 2 is the second or “right” term. The number three is their sum.
Let’s return to the solution of our “addition” problem. In it, the second term must be reduced by 19, then the sum will not change.
