If x satisfies the equation x - (3a + 1) = 2x + 2A + 1 and the inequality X-1 minus 2x-3 ≤ 1, the range of a is
∵x-(3a+1）=2x+2a+1
∴x=-5a-2
∵3/（x-1）-3/（2x-3）≤1
Substitute x = - 5a-2 to get
3/（-5a-3）-3/（-10a-7）≤1
After general division, it can be reduced to (- 15a-12) / (5a + 3) (10a + 7) ≤ 1
A ≤ - 1 or a ≥ 0.7
If the solutions of equation 2x-3 = 3 and 1-3a-x / 2 = 0 are the same, what is the value of a?
2x-3=3
x=3
If 1-3a-x / 2 = 0
1-3a-3/2=0
a=-1/6
