a + 3a + 5a = 180 9a =180 a = 20

Answer to: 5a + 1 = a - 3a = -1

12a

2a + 3a = 5a

2a + 3a + 4 = 5a + 4

If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1

1a (or just a for short).

13a - 6 + a = 5a + 3 + 3a 13a + a - 5a - 3a = 3 + 6 6a = 9 6a/6 = 9/6 a = 3/2

2a + 5a + 3a = 10a

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

6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b

From your description, I get: a + b + c = 180b - 3a c = 5a You have two equations and three unknowns, which is unsolvable.
