Step-by-step explanation:
Total postcards boys have = 280
Let,
x = Paul's postcards
y = Shawn's postcards
z = Tim's postcards
According to given statement;
x + y + z = 280 Eqn 1
Eqn 2
Eqn 3
Putting value of y from Eqn 3 in Eqn 2
Eqn 4
Putting value of x and y from Eqn 4 and Eqn 3 in Eqn 1
Multiplying both sides by
Putting z=120 in Eqn 3
Putting y=96 in Eqn 2
Difference of Tim and Paul = 120-64 = 56
Tim has 56 more postcards than Paul.
