Answer 1

$\frac{5}{18} + (x + 11) = 1 \frac{9}{10 } \\ x = 1 \frac{9}{10} - \frac{5}{18} - 11 \\ x = \frac{9}{2 \times 5} - \frac{5}{2 \times 9} - 10 \\ x = \frac{9 \times 9 - 5 \times 5}{2 \times 5 \times 9} - 10 \\ x = \frac{81 - 25}{90} - 10 \\ x = \frac{56}{90} - 10 \\ x = \frac{28}{45} - 10 \\ x = - 9 \frac{17}{45}$
