1. multiply by 3: 6a + 12b - 4a
2. do the arithmetic: 6a-4a = 2a
3. include the 'b' variable: 2a + 12b
4. divide by a common number; in this case = 2
5. a + 6b
Unless your dash is a -3, then just follow the pattern above. One can also solve for each variable:
1. a = 6b
2. a/6 = b
Is this what you wanted?

Simplifying
-3(2a + 4b) + -4a
(2a * -3 + 4b * -3) + -4a
(-6a + -12b) + -4a
Reorder the terms:
-6a + -4a + -12b
Combine like terms: -6a + -4a = -10a
-10a + -12b
-10a -12b

2a + 12 b
if the problem was '3(2a + 4b) -4a
-10a -12b
if the problem was '-3(2a +4b) - 4a
Do not use the answers given by others unless they match one of these, choose which problem was the correct one. Trust me, i've taken college calc classes.

I am not sure which one you mean.
3(2a + 4b) - 4a = 6a + 12b - 4a = 2a + 12b = 2(a + 6b)
-3(2a + 4b) - 4a = -6a - 12b -4a = -10a - 12b = -2(5a + 6b)

- 3(2a + 4b) - 4a
Use the distributive property:
(-6a+-8b)-4a
Now, combine like terms (subtract the -4a):
-2a+8b
Simplify:
-2 (a-4b)

=-3*2a+(-3)*4b-4a
=-6a-12b-4a
=-10a-12b
=-2(5a+6b)

- 3(2a + 4b) - 4a?
-6a - 12ab - 4a
-10a - 12ab
2a(-5 - 6b) < -- the answer I think

-3(2a + 4b) - 4a
= -6a - 12b - 4a
= -6a-4a -12b
=-10a - 12b
= - 2( 5a + 6b)
