Daca numarul rational 2/3 este solutie pentru ecuatia: a) 2-x=4/3

Answer 1

[tex]2-x= \frac{4}{3} \\ \\ Daca~x= \frac{2}{3},~atunci: \\ \\ 2- \frac{2}{3}= \frac{4}{3} \\ \\ Il~amplifici~pe~2~cu~3: \\ \\ \frac{6}{3}-\frac{2}{3}= \frac{4}{3}|*3 \\ \\ 6-2=4 => \\ \\ => \frac{2}{3}~este~solutia [/tex]
