Answer 1

Answer:

May be this will help you and please put this answer in brain list

Step-by-step explanation:

Here are a couple hints to turn this into an equation:

"Less than" means subtraction, whereas "more than" means addition.

Saying "twice a number" means that you are multiplying that number by 2

I will put the "7 less than" last, since it will be subtracted from the rest of the equation:

"twice a number"

⇒

2

n

"and k" (This means that it is twice  

n

and twice  

k

, or they are both multiplied by 2)

⇒

2

n

k

But this is lessened by  

7

:

"7 less than"

⇒

2

n

k

−

7

So the phrase translated into an equation is:

2

n

k

−

7
