Question

Решите умоляю!!!!!!!!!!!!!!!

Answer 1

1)4х+7(х-2)<10-2(3х-5)
4х+7х-14<10-6х+10
11х-14<20-6х
11х+6х<20+14
17х<34
х<2
2)х÷3-1<=х÷4 нужно умножить на 12
4х-12<=3х
4х-3х<=12
х<=12
3)1-5-х÷2>=3х+2х-3÷5
10-5(5-х)>=30х+2(2х-3)
10-25+5х>=30х+4х-6
-15+5х>=34х-6
5х-34х>=-6+15
-29х>=9
х<=-9÷29
4)( t-1)^2>=(t-4)(t-3)
t^2-2t+1>=t^2-3t-4t+12
-2t+1>=-3t-4t+12
-2t+1>=-7t+12
-2t+7t>=12-1
5t>=11
t>=11÷5
