Question

Напишите пожалуйста номер восемь уравнение очень срочно

Answer 1

a)x=1-2/3=3/3-2/3=1/3

b)x=1/2- 4/5 = 5/10-8/10 = -3/10

c)x=1/3-7/20 = 20/60-21/60 = -1/60

d) x=17/18+ 5/16 = 17*8/144 + 5*9/144 = 136/144+45/144= 181/144

e)x=-10/9+17/18 = -20/18+17/18 = -3/18=-1/6

ё)x=-8/9-17/18 = -16/18-17/18 = -33/18

ж)x=-7/9-13/18 = -14/18-13/18 = -27/18=-3/2
