Answer:
15
Step-by-step explanation:
6 times 3 equals 18, then you subtract 3 from that and thats the answer
Remember you can do anything to an equation as long as you do it to both sides
2b+3c=14
minus 3c both sides
2b=14-3c
divide both sides by 2
Answer: 
Step-by-step explanation:
For this exercise it is necessary to remember the following:
1) The Distributive Property states the following:

2) The multiplication of signs:

Knowing this, and having the following expression given in the exercise:

You can apply the Distributive property multiplying
and
, which are inside the parentheses, by
.
So, you get the following result:

Answer:
23 x + 62
Step-by-step explanation:
Simplify the following:
5 (4 x + 12) + 3 x + 2
5 (4 x + 12) = 20 x + 60:
20 x + 60 + 3 x + 2
Grouping like terms, 60 + 20 x + 3 x + 2 = (20 x + 3 x) + (60 + 2):
(20 x + 3 x) + (60 + 2)
20 x + 3 x = 23 x:
23 x + (60 + 2)
60 + 2 = 62:
Answer: 23 x + 62
