[tex](y \div 2) \times 3=10.3[/tex]
[tex]y \div 2 = 10.3 \div 3[/tex]
[tex]y \div 2 = 103 \div 30[/tex]
[tex] y = 103 \div 30 \times 2[/tex]
[tex] y = 103 \times 2 \div 30[/tex]
[tex] y = 206 \div 30[/tex]
[tex]y = \frac{103}{15} = 6\frac{13}{15} \approx 6.866666667[/tex]
sper ca ti-am fost de folos. Success!!
