Answer:

$\boxed{\boxed{\sf x=-3}}$

Step-by-step explanation:

$\sf y = -3x - 2$

$\sf y=7$

We'll substitute y into the equation:

$\sf 7 = -3x - 2$

Switch sides:

$\sf -3x-2=7$

Add 2 to both sides

$\sf -3x-2+2=7+2$

$\sf -3x=9$

Divide both sides by -3:

$\sf \cfrac{-3x}{-3}=\cfrac{9}{-3}$

$\sf x=-3$

Therefore, the value of x/solution is -3

Ok to start this problem you must list two numbers that add to 14

7 and 7

9 and 5

10 and 4

6 and 8

those are the numbers that we will use for now..

Now multiply each pair of numbers and see which one equals 45

7 * 7 = 49, no

9 * 5 = 45, YES

10 * 4 = 40, No

6 * 8 = 48, No

The numbers discovered are 9 and 5

Sam has twice as many books as Jim. If Sam gives 12 books to Jim, they will have the same number of books. How many books do the

Neko [114]

Alright, lets get started.

Suppose number of books Jim have = x

Sam has twice as many books as Jim. So,

Number of books Sam have = 2x

If Sam gives 12 books to Jim, they will have the same number of books.

When Sam gives 12 books, his remaining books will be $= 2x - 12$

When Jim gets 12 books from Sam, his books will be $= x + 12$

And as per given question, they both now have equal books, so

$2x - 12 = x + 12$

Adding 12 in both sides

$2x - 12 + 12 = x + 12 + 12$

$2x = x + 24$

Subtracting x from both sides

$2x - x = x + 24 - x$

$x = 24$

It means Jim has number of books = 24

So, Sam has numberof books = $24 * 2 = 48$

So, they have number of books together = $24 + 48 = 72$ : Answer

Hope it will help :)
