Question

Determinati x astfel incat:
3,(2)+x<9,(7) in N

Answer 1

3,(2)+x<9,(7)
x<9,(7)-3,(2)
x<6,(5)
x∈N
x∈(0,1,2,3,4,5,6.)

Answer 2

$\displaystyle 3,(2)+x\ \textless \ 9,(7) \\ \frac{29}{9} +x\ \textless \ \frac{88}{9} \\ x\ \textless \ \frac{88}{9} - \frac{29}{9} \\ x\ \textless \ \frac{59}{9} \\ x\ \textless \ 6,(5) \\ x \im \{0;1;2;3;4;5;6;\}$
