The given information compares the numbers of messages from both Regina and Gabriel to the number sent by Felipe. So use the number sent by Felipe as the variable.
let x = # sent by Felipe
then x+7 = # sent by Regina
and 4x = # sent by Gabriel
The total number of messages was 103:
(x)+(x+7)+(4x) = 103
