The given expression can be simplified to: 3b-a
-2a plus 3b
3a + (3b - 2a) + 5b =3a + 3b - 2a + 5b =(3a - 2a) + (3b + 5b) =a + 8b
(5a - 4b) + (2c - 3b - 6c) + a =5a - 4b + 2c - 3b - 6c + a =(5a + a) + (-4b - 3b) + (2c - 6c) =[ 6a - 7b - 4c ].
plot point c so its distance from the origin is 1
6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)
A level 5a is higher. This is how it works: n 1c 1b 1a 2c 2b 2a 3c 3b 3a 4c 4b 4a 5c 5b 5a ect. Student from BGP. N.S.S
2a + 5a + 3a = 10a
-8a + 3a = (-8 + 3)a = (5)a = 5a
2a - 5a = -3a
