Answer 1

ANSWER

$-3$

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;

$\begin{gathered} -2x=6 \\ \frac{-2x}{-2}=\frac{6}{-2} \\ x=-3 \end{gathered}$

Therefore, the number is - 3
