3a + 6b - 3a
The 3a and (-3a) cancel out
Leaving you with 6b
The answer: d. 6b

Answer:

d. 6b

Step-by-step explanation:

Simplify the following:

[tex] \longrightarrow [/tex] 3(a + 2b) - 3a

3(a + 2b) = 3a + 6b:

[tex] \longrightarrow [/tex] 3a + 6b - 3a

Grouping like terms,

3a + 6b - 3a = 6b + (3a - 3a):

[tex] \longrightarrow [/tex] 6b + (3a - 3a)

3 a - 3 a = 0:

[tex] \longrightarrow [/tex] 6b
