Answer 1

a)2x-5,3=0,78
2x=0,78+5,3
2x=6,08
x=3,04
b)13-(x-1)=2,4
13-x+1=2,4
-x=2,4-1-13
-x=-11,6/*(-1)
x=11,6
c)3,(2)+x<9,(7)
29/2+x<88/7
203+14x<176
14x<176-203
14x<-27
x<-27/14

Answer 2

a)2x-5,3=0,78
2x=0,78+5,3
2x=6,08
x=6,08:2
x=3,04
b)12-(x-1)=2,4
x-1=12-2,4
x-1=9,6
x=9,6+1
x=10,6
c)3,(2)+x<9,(7) in N
29/9+x<88/9
x<88/9-29/9
x<59/9
x<6,(5)
x€{0;0,(1);0,(2);...;6,(4)}
