Answer:
5
Step-by-step explanation:
Let's call the original number x.
So, the first student did x+23, and the other student did x-1.
You know that the first students result was 7 times larger than the other students. So, you can make the equation:
x+23=7(x-1)
x+23=7x-7
Then, do the algebra
-6x=-30
x=5
Answer:
-1.1
Step-by-step explanation:
The numbers in these -> | brackets indicate absolute number which means the numbers between them are always end up positive
Just follow regular BEDMAS/PEDMAS:
|-19+(9/3)| - |14-(22/9)|
|-19+3| - |14-2.444|
|-16| - |11.556|
Then at the end make sure the numbers are all positive:
|16| - |11.556| OR just 16 - 11.556
= 4.444
Answer:
x = 2, y = 4
Step-by-step explanation:
3x - y = 2
3(2) - (4) = 2
6 - 4 = 2
x + y = 6
(2) + (4) = 6
6 = 6
