Answer 1

`-3`

Step-by-step explanation

Given

Let the number be represented by x

5 less than a number is;

`x-5.............1`

1 more than three times the number can be written as;

`1+3x............2`

Since they are equal, hence we have;

`x-5=1+3x`

Solving for x;

`\begin{gathered} x-5=1+3x \\ x-3x=1+5 \\ -2x=6 \end{gathered}`

Divide both sides by -2;

`\begin{gathered} -2x=6 \\ (-2x)/(-2)=(6)/(-2) \\ x=-3 \end{gathered}`

Therefore, the number is - 3
