The solution of the equation 5x-2m = - 4-x of X satisfies that 2 is less than X and 10 is less than x, and the value range of M is obtained
5x-2m=-4-x
m=3x+2
2 less than x less than 10
6 less than 3x less than 30
8 less than 3x + 2 less than 32
8 less than m less than 32
If the solution of the equation 5x-2m = - 4-x is between 2 and 10, then the value range of M is ()
A. M ＞ 8b. M ＜ 32c. 8 ＜ m ＜ 32D. M ＜ 8 or m ＞ 32
The solution of equation 5x-2m = - 4-x is: x = m − 23, ∵ the solution of equation is between 2 and 10, that is, 2 ∵ m − 23 ∵ 10, ∵ 8 ∵ m ∵ 32
