Question

completeaza:a=13supra 6 a+b=3 b=?.

Answer 1

[tex] a=\frac{13}{6}\\ a+b=3 \\ \Leftrightarrow \\ \frac{13}{6}+b=3 \\ \Leftrightarrow \\ b=3-\frac{13}{6}\\ \Leftrightarrow \\ b=\frac{3*6-13}{6}\\ \Leftrightarrow\\ b=\frac{18-13}{6} \\\Leftrightarrow \\ b=\frac{5}{6}\\ a+b=\frac{13}{6}+\frac{5}{6}=\frac{13+5}{6}=\frac{18}{6}=3[/tex]
