Question

Find a number such that when 5 is subtracted from 5 times the number, the result is 4 more than twice the number.

Answer 1

$$\begin{gathered} \mathrm{Let}\mathrm{the}\mathrm{number}\mathrm{be}\mathrm{x}. \\ \mathrm{According}\mathrm{to}\mathrm{the}\mathrm{question}, \\ 5\mathrm{x}-5=2\mathrm{x}+4 \\ \mathrm{or}5\mathrm{x}-2\mathrm{x}=4+5 \\ \mathrm{or}3\mathrm{x}=9 \\ \mathrm{or}\mathrm{x}=\frac{9}{3} \\ \mathrm{or}\mathrm{x}=3 \\ \mathrm{Thus},\mathrm{the}\mathrm{number}\mathrm{is}3. \end{gathered}$$
