If the solution of the equation 2x + 1 = 3x is the same as that of the equation x-3a = 4 about X, find the solution of the equation − 12ay + 1 = 32y + 5 about y

If the solution of the equation 2x + 1 = 3x is the same as that of the equation x-3a = 4 about X, find the solution of the equation − 12ay + 1 = 32y + 5 about y

Equation 2x + 1 = 3x, the solution is: x = 1, substituting x = 1 into equation x-3a = 4, the solution is: 1-3a = 4, that is, a = - 1, substituting a = - 1 into: 12Y + 1 = 32y + 5, the solution is: y = - 4

Let's do it with a linear equation of one variable,
When a ship sails between a and B, it takes 3 hours to go downstream and 30 hours more to go upstream than to go downstream

Let the water velocity be AKM / h
3×（a+26）=(30+3)(26-a)
3a+78=858-33a
36a=780
A = 21 and 2 / 3
A: the water speed is 21.2/3km/h

To solve the problem with a linear equation of one variable)
Last week, my mother bought several boxes of milk with 36 yuan in the supermarket. Today, she came to the supermarket again and found that the last box of milk sold at 0.3 yuan. So my mother spent another 36 yuan to buy this kind of milk. As a result, she found that she bought four more boxes than before. What was the original selling price of this kind of milk?

Suppose the original selling price of this kind of milk is x yuan
36/（x－0.3）－36/x＝4
36x－36/（x－0.3）＝4x*(x-0.3)
x＝1.8

What are the steps to solve the equation of first degree with one variable?
There are five steps to solve the linear equation of one variable
Step one:
Go to the denominator, see what the least common multiple of these denominators is, and multiply each item by this number
Step 2:
What is the number obtained by dividing the bracket with the least common multiple? Multiply the number by the numerator, but some of the numerator should be enclosed in brackets. If there is an integer, copy it
Step 3:
If you want to move the right term over the left, you also need to change the sign
Step 4:
Merge the similar items, move the similar items to one side, and then start to merge
Step 5:
If the coefficient is changed to 1, it is necessary to get a number according to the basic properties of the equation. If two numbers are multiplied to get a number, it is necessary to divide by the number on the side with the unknown number. Pay attention to divide by the number on both sides, and finally get the unknown number

Step 1: go to the denominator, see what the least common multiple of the denominator is, and multiply each item by this number. Step 2: go to the bracket, and what is the number obtained after dividing with the least common multiple, and multiply this number by the numerator, but some of the numerator should be bracketed, if there is an integer, it will be copied. Step 3: move the term, that is, the number on the left side of the equation
