Question

The sum of two integers is $12$. If one of them is $-20$, find the other integer.

Answer 1

Addition and Subtraction of Integers

Sum of integers $=12$

One of integer = $-20=a$

Let the second integer be $b$.

$$\begin{gathered} Soa+b=12 \\ or-20+b=12 \\ orb=12+20 \\ orb=32 \end{gathered}$$

Therefore, the second integer is $32$.
