Question

Решите уравнение 31/76 + 45/76 - p = 15/31 и 13/58 + 21/58 - m = 6/29.

Answer 1

$\frac{31}{76}+ \frac{45}{76}-p= \frac{15}{31} , \\ \frac{31+45}{76}-p= \frac{15}{31} \\ \frac{76}{76}-p= \frac{15}{31} \\ 1-p= \frac{15}{31} \\$
$p=1+ \frac{15}{31} \\ p=1 \frac{15}{31}$

$\frac{13}{58}+ \frac{21}{58}-m= \frac{6}{29} \\ \frac{13+21}{58}-m= \frac{6}{29} \\ \frac{34}{58}-m= \frac{6}{29} \\ \frac{17}{29}-m= \frac{6}{29} \\ m=\frac{17}{29}-\frac{6}{29} \\m=\frac{17-6}{29} \\ m=\frac{11}{29} \\$
