Question

Решите 11х-5/8=2 7/12 и 27/28х+5/4=3 17/28

Answer 1

11х - 5/8 = 2 7/12,
11х =  2 7/12 + 5/8,
11х = 31/12 + 5/8,
11х = 62/24 + 15/24,
11х = 77/24,
х = 77/24 : 11,
х = 77/24 * 1/11,
х = 7/24,

27/28х + 5/4 = 3 17/28,
27/28х = 3 17/28 - 5/4,
27/28х = 2 45/28 - 35/28,
27/28х = 2 10/28,
27/28х = 66/28,
х = 66/28 : 27/28,
х = 66/28 * 28/27,
х = 22/9,
х = 2 4/9

Answer 2

11x-5/8=2 7/12
11x-0,625=31/12
11x=31/12+0,625
11x=31/12+5/8
11x=77/24
x=7/24

27/28x+5/4=3 17/28
27/28x+1,25=101/28
27/28x+5/4=101/28
27x+35=101
27x=101-35
27x=66
x=22/9
