If the sum of two integers is 34 and one of them is -12, we can find the other integer by subtracting -12 from 34.
Let's denote the other integer as xx.
Given: One integer is -12. The sum of the two integers is 34.
We can set up the equation: x+(−12)=34x+(−12)=34
To solve for xx, add 12 to both sides of the equation: x=34+12x=34+12 x=46x=46
So, the other integer is x=46x=46.
