Question

4/15-х=1/6

(х+1/4)1/5=6. 3/10​

Answer 1

Пошаговое объяснение:

4/15 - х = 1/6

х = 4/15 - 1/6

х = 8/30 - 5/30

х = 3/30

х = 1/10

(х + 1/4)1/5 = 6 3/10

х + 1/4 = 6 3/10 : 1/5

х + 1/4 = 63/10 * 5/1

х + 1/4 = 63/2 * 1/1

х + 1/4 = 63/2

х + 1/4 = 31 1/2

х = 31 1/2 - 1/4

х = 31 2/4 - 1/4

х = 31 1/4
