Пошаговое объяснение:
(х - 5)/3 = 8
х - 5 = 8 * 3
х - 5 = 24
х = 24 + 5
х = 29
(6х + 7)/7 = (5х - 3)/8
8(6х + 7) = 7(5х - 3)
48х + 56 = 35х - 21
48х - 35х = -21 - 56
13х = -77
х = -77 : 13
х = -77/13
х = -5 12/13

x-5=3•8=24
x=29
2) 6x+7/7=5x-3/8
8(6x+7)=7(5x-3)
48x+56=35x-21
48x-35x=-21-56
13x=-77
x=-77/13
