Answer:
-3(-4a - 2) = 12a + 6
Step-by-step explanation:
-3(-4a - 2)

-3 * -4a = 12a
-3 * -2 = 6
=> combine like terms
12a + 6

答案是 NO.c
Step-by step:
第一的，
-3=2x+3
-6=2x
因此，x= -3
第二，
2x+3=5
2x=5-3
2x=2
因此, x=1
The answer is clearly 4 and 1. If we change the sign on 1 (making it -1), then you have the answer to your original question. 4 and -1 multiply to -4 and add up to 3.
