Whats 4a + 3b - 2a - b + a - 6b simplified?

4a - 2a + a + 3b - b - 6b
3a - 4b

4a+3b-2a-1b= 2a+2b
2a+2b+1a-6b= 3a-4b.

or
4a-2a+1a= 3a
3b-1b-6b= -4b
=3a-4b.

this is easy..

4a + 3b -2a - b + a - 6b

(4a - 2a + a) + (3b - b - 6b) ; grouping

3a - 4b

do u got it now?

2a+3b-b+a-6b
3a+2b-6b
= 3a - 4b
=)

3a - 4b.

Regroup

(4a - 2a + a) + ( 3b - b - 6b)

3a + - 4b
or 3a - 4b

4a + 3b - 2a - b + a - 6b
= 4a - 2a + a + 3b - b - 6b
= 2a + a + 2b - 6b
= 3a + (-4b)
= 3a - 4b

You have to group the a's together and then the b's.

4a - 2a + a = 3a
3b -b-6b = -4b
So it's 3a - 4b.
Remember the sign in front of the number always travels with the number.

4a + 3b - 2a - b + a - 6b

+ and - the As and Bs

= 3a - 4b

4a - 2a + a +3b -b -6b
3a - 4b
