According to the condition: the difference between one third of a certain number and one fourth of the number is 15, let a certain number be x, then the equation listed is?

According to the condition: the difference between one third of a certain number and one fourth of the number is 15, let a certain number be x, then the equation listed is?

One third x minus one fourth x = 15 one twelfth x equals 15 x equals 180

According to the following conditions, let a certain number be x, we can list the equation - one-third x = 6, but the quotient of a.6 and (- 3) is equal to one-third of a certain number B
It is equal to 6 C, one-third of the difference between a certain number and 1 D, and one-third of the opposite number of a certain number is 6

-One third of X is one third of the opposite of X
So choose D

If 70% of a number minus 2 / 3 of the difference of 6 is 32, let X be the number, then the equation is

Let this number be X
（70%x-6）×2/3=32
70%x-6=48
70%x=54
x=540/7

Given that the solution of X − 1x + 2 − XX − 1 = m (x + 2) (x − 1) is negative, try to find the value range of M

To get: (x-1) 2-x (x + 2) = m, the solution is: x = 1 − M4, from the topic meaning: 1 − M4 < 0 and 1 − M4 ≠ - 2, and 1 − M4 ≠ 1, the solution is: M > 1 and m ≠ 9
