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

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



If the solutions of the equations 5x + 3 = 8x-3 and 5x + a = 14 of X are opposite to each other, then a=


5x1+3=8x1-3
-3x1=-6
x1=2
∴x2=-x1=-2
∴5x+a=14
-10+a=14
a=-4



At 3.5 + X, 6 + 5x


(8x-5x = 2.4) is the equation
(6+5x



The solution of the equation 5x-2k = - x + 4 is greater than 1 but less than 3


5x-2k=-x+4
That is K + 2 = 3x
1 〈 x 〈 3
So 1 (K + 2) / 3 (3)
So 1 〈 K 〈 7
That is, k = 2,3,4,5,6
