Solution: According to the problem, if you plan to eat x days, then, 4x+8=6x-42
x=254x25+8=108
So, I planned to eat it for 25 days, and my mother bought back 108 apples.
-
Solution: Let the planned number of days be x days and the total number of apples will be y.
4x+8=y
6x-42=y
That is: 4x+8=6x-42
x=25 (days).
That is: 4*25+8=y
y=108 (pcs).
A: Mom bought back 108 apples and planned to eat them for 25 days.
-
x number of apples y number of days planned.
Derived from the suggestion:
1,x-y4=8
2,6y-x=42 is calculated as y=25 by adding 2 to 1 (6y-x)+(x-4y)=42+8
Substituting y=25 into 1 gives x-100=8 and we get x=108, so I bought 108 apples and planned for 25 days.
-
<> suppose there are x days: eat 4 apples a day, eat a total of 4x apples and have 8 more apples, which can be expressed as: buy a total of x apples - eat a total of 4x apples = 8 i.e.: x-4x=8 solution: x=12 So, my mother bought 12*4 = 48 apples.
-
Solution: Let the apple be x and the number of days y
then, x-4y=8
42+x=6y
x=8+4y
6y=42+8+4y
y=25x=108
Therefore, my mother bought 108 apples and planned to eat them for 25 days.

Summary. x=48+8 56 represents the total number of apples.
The answer is: (6-4)x=48 What does 8 mean?
Mom bought back a basket of apples, and ate four more apples a day according to the planned number of days, and there were 48 more; Eat six a day, eight less. How many apples did Mom buy back?

You've done a great job! Can you elaborate on that?
The answer is: (6-4)x=48 What does 8 mean?

Mom buys back 160 apples.
The process is as follows:
Solution: Let my mother plan to eat for x days.
4x+48=6x-8
6x-8=4x+48
2x=562x÷2=56÷2
x=2828 4+48=160 (pcs).
-
If you plan to eat x days, you will buy 4x+48 apples 4x+48=6x-8 and solve x=28 days, a total of 28 6-8=160 apples.
-
Solution: Let's eat for x days.
4x+48=6x-8
6x-4x=48+8
2x=56x=28
28 4 + 48 = 160 pcs.
A: There are 160 apples in total.
-
Bought 160 apples and planned to eat them for 28 days
-
Solution: Let's eat for x days.
4x+48=6x-8
6x-4x=48+8
2x=56x=28
28 4 + 48 = 160 pcs.
A: There are 160 apples in total.

Cheng Yushan, hello:
This is a typical P&L problem, the number of days planned:
28 (days) Number of apples:
160 (pcs).
-
Suppose x apples are bought, and the number of days is the same, so the equation ( x-48) 4=(x+8) 6 is solved to x=160
-
Solution: Set a plan to eat x days. According to the title:
4x+48=6x-8
56=2xx=28
28x4+48=160 (pcs).
A: Plan to eat it for 28 days, a total of 160 apples.
-
4x+48=6x-8
Dismiss x=28
The number of apples is 160.
-
y=4x+48
y=6x-8
solution, y=128
x is the number of days, and y is the number of days.
Let Xiao Hong be 2x and Xiao Ming (x+15).
So 2x+(x+15)=300 gives x=95 >>>More
Liu Bowen sent fish to imply that Zhu Yuanzhang killed people, without fish, Zhu Yuanzhang, a fish farmer, would not have to starve to death. And Zhu Yuanzhang only understood that his sons would rebel after listening to his grandson's words 17 years later, and only then did he understand Liu Bowen's good intentions.
Folklore has it that Liu Bowen sent a basket of fish to Zhu Yuanzhang before he died, and when the basket of fish was sent to Zhu Yuanzhang, some of the fish were alive, but it didn't take long for these fish to die because of biting each other, Zhu Yuanzhang suddenly realized after many years that Liu Bowen's basket of fish represents the descendants of the Zhu family, and if they are put together to compete for the throne, it will only make them live and die, so Zhu Yuanzhang divided the land for the children and kept them away from the capital. Of course, this is really just folklore.

In this question, let's first look at "3 left in the average score of 7 people, and 2 left in 8 people", we can see that if there is no remainder, if we want to find out the number of numbers where the product of 7 is less than the product of 8 and the product "1", we use the enumeration method to be more intuitive: >>>More
