Question

(39/13+x) -5 8/13=1 7/13 пожалуйста​

Answer 1

$( \frac{39}{13} + x) - 5 \frac{8}{13} = 1 \frac{7}{13} \\ (3 + x) - 5 \frac{8}{13} = \frac{20}{13} \\ 3 + x - 5 \frac{8}{13} = \frac{20}{13} \\ 3 + x - \frac{73}{13} = \frac{20}{13} \\ - \frac{34}{13} + x = \frac{20}{13} \\ x = \frac{20}{13} + \frac{34}{13} \\ x = \frac{54}{13}$
