8b -2a
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
add like terms: 3a -2a -5b + 6b +3b - 7b = a -3b
ok, let's see: (3a-2a) + (2b+5b) +(-c +3c) = a + 7b +2c I think that's right.

the answer
2a+5b isn't possible the answer is still 2a+5b.
3a + (3b - 2a) + 5b =3a + 3b - 2a + 5b =(3a - 2a) + (3b + 5b) =a + 8b
What is the solution of -2a plus 3a plus 5b
8b -2a
The expression is: (4a+b)/(2a-5b)
2a+6b
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
add like terms: 3a -2a -5b + 6b +3b - 7b = a -3b
10a - 5b = 25 So 5b = 10a - 25 and hence b = 2a - 5
ok, let's see: (3a-2a) + (2b+5b) +(-c +3c) = a + 7b +2c I think that's right.
