The unknown number is 46.
A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Let the number be x.
The sum of 74 and four times a number is 258,
⇒ [tex]74+4x=258[/tex]
⇒ [tex]4x=258-74[/tex]
⇒ [tex]x=\frac{184}{4}[/tex]
⇒ [tex]x=46[/tex]
Hence we can conclude that the unknown number is 46.
