Answer provided by our tutors
let
j = the weight of Joe
c = the weight of Craig
d = the weight of Dylan
Joe, Craig and Dylan have a combined weight of 326 pounds
j + d + c = 326
Craig weighs 40 more pounds and Joe
c = 40 + j
Dylan weighs 12 pounds more than Craig
d = 12 + c
by solving the system of equations
j + d + c = 326
c = 40 + j
d = 12 + c
we find
j = 78 lbs the weight of Joe
d = 130 lbs the weight of Dylan
c = 118 lbs the weight of Craig
