Answer 1

Ответ:

Пошаговое объяснение:

$\frac{x-5}{4}=7 - \frac{2x-11}{3} \\\frac{x-5}{4}+\frac{2x-11}{3}=7\\\frac{3x-15+8x-44}{12}=7\\ \frac{11x-59}{12}=7\\ 11x - 59 = 7 * 12\\11x - 59 = 84\\11x = 84 + 59\\11x = 143\\x = 143 : 11\\x = 13$

$5+\frac{7x-12}{3}= x+13\\\frac{7x-12}{3}-x=13-5\\ \frac{7x-12}{3}-x=8\\\frac{7x-12-3x}{3}=8\\ \frac{4x-12}{3}=8\\4x-12=8*3\\4x-12=24\\4x=24+12\\4x=36\\4x=36:4\\x=9$
