Question 528539
Let {{{s}}} = sum of scores of all 16 students in class
Let {{{h}}} = the highest score of the 16 students
With all the students in class:
(1) {{{ 83 = s / 16 }}}
With highest score taken away:
(2) {{{ 82 = ( s - h ) / 15 }}}
------------------
This is 2 equations and 2 unknowns, so it's solvable
(1) {{{ s = 16*83 }}}
(2) {{{ 15*82 = s - h }}}
Substitute (1) into (2)
(2) {{{ 15*82 = 16*83 - h }}}
(2) {{{ h = 16*83 - 15*82 }}}
