number 2 : y

A.T.Q.:

x = 5 + 2 y

x + y - 10 = 5

x = 5 + 2 y, x + y - 10 = 5 : x = \frac{35}{3}, y = \frac{10}{3}

Convert improper fractions to mixed numbers:

\frac{35}{3} = 11 \frac{2}{3}

Convert improper fractions to mixed numbers:

\frac{10}{3} = 3 \frac{1}{3}

The numbers : 11 \frac{2}{3}, 3 \frac{1}{3}
