Answer provided by our tutors
Let
m = the weight of Michael
p = the weight of Peter
Michael weighs 42 more pounds that Peter:
m = 42 + p
The sum of their weights is 286 pounds:
m + p = 286
By solving the system:
m = 42 + p
m + p = 286
........
........
m = 164 lbs
p = 122 lbs
Peter weights 122 lbs.
