286-42=144
144\2=122
122(peter)+164(malco)=286(total weight)

So, let's establish some variables:

P = Peter
M = Malco = P + 42


Now let us establish an equation to find for P:
268 = P + P + 42
268 = 2P + 42
268 - 42 = 2P
226 = 2P
226 / 2 = P
113 = P


Now to find for M:
P + M = 268
113 + M = 268
M = 268 - 113
M = 155


Answer:
Peter = 113 pounds
Malco = 155 pounds
