Артурка · Answer 1

3/4:1/8 (х+3) - 1/2=5/14

3/4: (1/8 х+3/8) = 5/14+7/14

3/4: (1/8 х+3/8) = 12/14

1/8 х+3/8=3/4:6/7

1/8 х+3/8=7/8

1/8 х=7/8-3/8

1/8 х=4/8

х=4/8:1/8

х=4

Марлеся · Answer 2

(3/4) : (1/8 х + 3/8) - (1/2) = 5/14

(3/4) : (1/8 х + 3/8) = 5/14 + (7/14)

(3/4) : (1/8 х + 3/8) = 6/7

(1/8) Х + (3/8) = (3/4) : (6/7)

(1/8) Х + (3/8) = 21/24

(1/8) Х = (21/24) - (9/24)

(1/8) Х = 1/2

Х = (1/2) : (1/8)

Х = 4
