解不等式(1)(y+1/6)-(2y-5/4)>=1+(y/2) (2)(x-3/2)+3>=x 1-3(x-1)

解不等式(1)(y+1/6)-(2y-5/4)>=1+(y/2) (2)(x-3/2)+3>=x 1-3(x-1)
解不等式(1)(y+1/6)-(2y-5/4)>=1+(y/2) (2)(x-3/2)+3>=x 1-3(x-1)

解不等式(1)(y+1/6)-(2y-5/4)>=1+(y/2) (2)(x-3/2)+3>=x 1-3(x-1)
第一题
两边乘12
2(y+1)-3(2y-5)>=12+6y
-4y+17>=12+6y
10y<=5
y<=1/2
第二题
(x-3/2)+3>=x
两边乘2
x-3+6>=2x
x<=3
1-3(x-1)<8-x
1-3x+3<8-x
2x>1+3-8=-4
x>-2
所以-2
