Answer:
The system of equations are
x+y=557

The total pages in shorter book is 245
The total pages in longer book is 312
Step-by-step explanation:
Given that,
Scott has read 407 of the total number of 557 pages, which
of the shorter book and
of longer book.
Total number of pages of shorter book be x and longer book be y.
Then,
page of the shorter book 
pages of the longer book = 
So, he has read 
Total number of pages of both book is = x+y
According to the problem,
x+y=557.........(1)
.......(2)
We can write equation (2) as



......(3)
Now 18 times of equation (1) subtract from equation (3)
18x+25y=12210
18x+18y=10026
- - -
_______________
25y-18y=12,210-10,026
⇒7y=2,184

⇒y= 312
Plug y=312 in equation (1)
x+312=557
⇒x=557-312
⇒x=245
The total pages in shorter book is 245
The total pages in longer book is 312
Answer:

Answer:
4a. 13
4b. -4
Step-by-step explanation:
2x-6/5 = 4 (Muti each side by 5)
2x-6 = 20
2x = 26 (Divide each side by 2)
x = 13
7- 2x/4 = 9
-2x/4 = 2 (Muti each side by 4)
-2x = 8 (Divide each side by -2)
x = -4
Answer: 78
Step-by-step explanation:
6(4+9)
use foil to distribute the 6 to the 4 and 9
6×4 + 6×9
24 + 54
⇒ 78
