The difference between 4 times and 3 of a certain number is equal to 1 / 3 of a certain number. If a certain number is x, then----
4x-3=x/3;
11x/3=3;
x=9/11;
2. Two times of the sum of a number and 3 is equal to 10----
2(y+3)=10;
y+3=5;
y=2;
3. The number of a is ten percent more than that of B. if the number of a is y, then----
B = y × (1 + 0.1) = 1.1y;
I'm very glad to answer your questions. Skyhunter 002 will answer your questions
If you don't understand this question, you can ask,

23, 59, 17 what's the next number?

The three numbers are generally difficult to decide. There is a way of thinking
twenty-three
23+36=59
59-42=17
17+48=65
65-52=13

Three times a number is 12.3 more than 17.4. What's the number?
(who can do me a favor, I'll give him a little more wealth value) a number of 5.7 times is 15.4 times more than 4.3 times. What's the number? (we have to use equations to solve it)

This number is X
3x-17.4=12.3
3x=12.3+17.4
3x=29.7
x=9.9
The number is three
5.7x-4.3x=15.4
1.4x=15.4
x=15.4÷1.4
x=11

There are 84 people in class 51 and class 52. Five eighths of class 1 and three fourths of class 2 are 58 people. How many people are there in each class?

Set class one as X, class two (84-x)
5 / 8 x + (84-x) 3 / 4 = 58
Five eighths x + 63 - three fourths x = 58
8 / 5 = 63 + 58
Three quarters X - five eighths x = 5
One eighth x = 5
X = 5 times 8
Class 1: x = 40
Class 2: 84-40 = 44

There are 84 students in class one and class two in five years. There are 58 students in class one in five years and class two in five years
Less people? Don't worry, hurry

Class 1: (84-58 * (1 △ 3 / 4)) / (1-5 / 8 △ 3 / 4) = 40 people class 2: 84-40 = 44 people

The sum of 6 times of a number plus the product of 6 and 8 is 84

(84-6*8)÷6=36÷6=6

5 times of a number plus the product of 3.2 and 0.5 is 36.6. Find the number (by solving the equation)

Let X be the number
5x+3.2*0.5=36.6
That is, 5x = 35
x=7
A: the number is 7

Lie equation: eight times of a number is 2.4 more than the product of 6.4 and 4.5. What's the number?

This number is X
8x-6.4*4.5=2.4
x=3.9

【1】 Five times of a number, plus the product of 1.5 and 3.6, and the sum is 10

5x + 1.5 * 3.6 = 10, x = 0.92

Solve the equation 9x-11 = 70

9x-11=70
9x=70+11=81
x=81/9=9
