Question

Rezolvati ecuatia: 2x-5,3 =0,78 si aflati xnumar natural, dqaca 3x+ 1<32,02

Answer 1

$2x-5,3=0,78 \\ 2x=0,78+5,3 \\ 2x=6,08 \\ x= \frac{6,08}{2} \\ x=3,04 \\ \\ 3x+1\ \textless \ 32,02 \\ 3x\ \textless \ 32,02-1 \\ 3x\ \textless \ 31,02 \\ x\ \textless \ \frac{31,02}{3} \\ x\ \textless \ 10,34$
