5x-2>3(x+1)
5x-2>3x+3
5x-3x>3+2
2x>5
x>2.5
1/2x-1<=7-3/2x
1/2x+3/2x≤7+1
2x≤8
x≤4
∴2.5<x≤4
解:解不等式5x-2>3(x+1),得
x>2.5
解不等式1/2x-1<=7-3/2x,得
x≤4
所以,不等式组的解集是:2.5<x≤4.
解:
解不等式5x-2>3(x+1),
得x>2.5
解不等式1/2x-1<=7-3/2x,
得x≤4
所以,不等式组的解集是:2.5<x≤4.
5x-2>3(x+1)→X>2.5
1/2x-1<=7-3/2x→X>=0.25
所以 此不等式组无解
x>5/2。
X<=4。
