Question 1146606

let's the certain number be {{{x}}}

the sum of a certain number and {{{16}}}: {{{x+16}}}

equal to five times the number:{{{5x}}}


if the sum of a certain number and {{{16}}} is equal to five times the number, we know that

{{{x+16=5x}}}.....solve or {{{x}}}

 {{{16=5x-x}}}

 {{{16=4x}}}

{{{x=16/4}}}

{{{x=4}}}

so, the number is {{{4}}}


check:

{{{x+16=5x}}}

{{{4+16=5*4}}}

{{{20=20}}}-> this confirms our solution
