Question

The sum of two rational numbers is (-8) and one of them is -3/2. Find the other.

Answer 1

$$\begin{gathered} \mathrm{Let}\mathrm{the}\mathrm{other}\mathrm{number}=\mathrm{x} \\ \mathrm{Now},\mathrm{according}\mathrm{to}\mathrm{question}, \\ \mathrm{x}+\left(-\frac{3}{2}\right)=-8 \\ \Rightarrow \mathrm{x}=-8+\frac{3}{2}=\frac{-16+3}{2}=-\frac{13}{2} \\ \mathrm{So},\mathrm{other}\mathrm{number}=-\frac{13}{2} \end{gathered}$$
