Ответ:
so... let us say, the amount of text for each is
Heather sent "h" amount
Ahmand sent "a" amount
and
Pablo sent "p" amount
so.. all three sent 76, meaning
h + a + p = 76
we know that, whatever "h" and "a" and "p" are
Pablo, send twice as much as Ahmad
so, if Ahmad sent "a", Pablo then sent 2 * a or 2a
Heather sent 8 less than Ahmad
so, if Ahmad sent "a", Heather then sent a - 8
thus
solve for "a", to find how many Ahmad sent
Heather sent 8 less than that
and
Pablo sent, twice as much
