Subtract 13 from both sides.
-13
-7 = -20
-2x = -20
Divide by 2 on both sides.
Remember: Negative divided by a negative makes a positive.
-2/-2 = 1
-20/-2 = 10
Your answer:
x = 10
The number of comic books is an illustration of a linear function
- The complete equations are:
and 
- The value of b has increased by 4
She had 17 comic books already.
So, we have:

Her order of 65 books contains 8 comic books per collection.
So, we have:


This is represented as:

So, we have:

Rewrite as:

Subtract 17 from both sides

Divide both sides by 8

Assume she has 97 books in her collection, then the equation would be represented as:

Subtract 17 from both sides

Divide both sides by 8

The values of b are 6 and 10.
The difference between 6 and 10 is 4
Hence, the value of b has increased by 4

Answer:
y = -x + 4
Step-by-step explanation:
x + y = 6 => y = -x + 6
The line that parallel to y = -x + 6 has same slope so m = -1
Using coordinates (-4,8)
y = mx + b
8 = (-1)(-4) + b
8 = 4 + b
b = 4
then y = -x + 4
