It simplifies to 5a+4 !
4a + 4b is one possible answer.
10a + 5b
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1

It simplifies to 5a+4 !
4a + 4b is one possible answer.
10a + 5b
Gathering like terms together, this is equal to 5a + 3b + 7c.
The given expression can be simplified to: 3b-a
30 + ab + 6b + 5a = 5(a+6) + b(a+6) = (b+5)(a+6)
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
-2
-2a plus 3b
It is: 5a+5b
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
