How to calculate 5x + 7 of 8 = X-5?

As your question is not clear, I will give the following answers:
1. (5x + 7) is a molecule
8(x-5)=5x+7
x=47/3
2.5x is a molecule
5x/8+7=x-5
x=32

3 / 1 of the sum of a number and - 2 and the difference between the number and 3 are equal (a series of equations)

Let this number be X
1/3 [x+(-2)]=x-3

What is 3.5 times of 10.5?

Let this number be X
3.5×X-10.5=0
3.5X=10.5
X=3
A: the number is 3

3 times of the difference of 2.5, 10.7 less than 5 times of this number, find the solution of some equation

Let this number be X
3(X-2.5)=5X-10.7
3X-7.5=5X-10.7
5X-3X=10.7-7.5
2X=3.2
X=3.2/2
X=1.6
This number is 1.6

The difference between five times of a number and nine is half of the number

Let this number be x, then 5 * x - 9 = x / 2; solving the linear equation of one variable, x = 2

Three eighths minus seven twelfth of a number is half. Find the number
What is the sum of two thirds divided by five sixths and three eighths?
Warehouse A is 210t less than warehouse B. It is known that the tonnage of warehouse B is 3.5 times that of warehouse A. how many tons of warehouse A and warehouse B are required!
(before 7:00, add 30 points!)
Yes, I'm 715059513

Let 2 / 3x △ 6 / 5 + 3 / 8 = 47 / 40
2. If the warehouse A is x tons, the warehouse B is (x + 210) tons
(x + 210) = 3.5x

If the algebraic expression 3x-2 and 12 are reciprocal, then the value of X is ()
A. 0B. 23C. -23D. 43

∵ the algebraic formula 3x-2 and 12 are reciprocal to each other, ∵ (3x-2) × 12 = 1, the solution is: x = 43, so D

Find the unknown X. (X-7): 4 = 8.4:2.12 × (2.8 + x) = 10.4

（1）（x-7）：4=8.4：2.1       2.1×（x-7）=4×8.4  2.1×（x-7）÷2.1=33.6÷2.1             x-7+7=16+7                  x=23；（2）2×（2.8+x）=10.4  2×（2.8+x）÷2=10.4÷2        2.8+x-2.8=5.2-2.8                x=2.4．
