a + b + c = 180
b = 3a
c = 5a
Substituting the values of b and c into the first equation.
a + 3a + 5a = 180 or 9a = 180 so that a = 20
then b = 3a = 3*20 = 60
and c = 5a = 5*20 = 100

a + 3a + 5a = 180 9a =180 a = 20
2a + 3a = 5a
The given expression can be simplified to: 3b-a
-8a + 3a = (-8 + 3)a = (5)a = 5a
3a + 2a = 5a
