let
x1 = the number of viewer Network 1 had
x2 = the number of viewer Network 2 had
x3 = the number of viewer Network 3 had
In a recent week, three television networks together averaged a total of 27.6 million viewers
x1 + x2 + x2 = 27.6
Network 1 had 1.4 million more viewers than Network 2
x1 = 1.4 + x2
Network 3 had 1.4 million fewer viewers than Network 2
x3 = 1.4 + x2
by solving the system of equations:
x1 + x2 + x2 = 27.6
x1 = 1.4 + x2
x3 = 1.4 + x2
we find:
x1 = 10.13 million viewers
x2 = 8.73 million viewers
x3 = 10.13 million viewers
