2. r + 4 = 39
To solve this problem, subtract the sum and the addend of the given equation.
![39 - 4 = \boxed{\sf 35}](https://img.qammunity.org/2022/formulas/mathematics/college/ptl6rrddckiq888t4rwg7hwr9h3faa5dgx.png)
Checking:
To check, simply substitute the conclusion on the unknown quantity.
35 (r) + 4 = 39
Thus, the equation was correct which gives us the answer that:
