The number of adults and children at the concert went was 61 and 44 respectively.
<h3>How to form an equation?</h3>
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
Let's suppose the number of adults who went to the concert was A while for children is C
Total people = adult + children
A + C = 105
Cost of adult = 3A
Cost of children = 3C
Total ticket = Cost of adult + Cost of children
3A + 3C = 271
By substitution,
A = 61 and C = 44
Hence "The number of adults and children at the concert went was 61 and 44 respectively".
