Răspuns:

Explicație pas cu pas:

13)

a)

2/3 - x = 11/6

x = 2/3 - 11/6 = 4/6 - 11/6 = -7/6

b)

8/5 + x = 7/10

x = 7/10 - 8/5 = 7/10 - 16/10 = -9/10

c)

17/6 - x = 3/4

x = 17/6 - 3/4 = 34/12 - 9/12 = 25/12

d)

13/4 + x = 9/10

x = 9/10 - 13/4 = 18/20 - 65/20 = -47/20

e)

9/14 - x = 5/4

x = 9/14 - 5/4 = 18/28 - 35/28 = -17/28

f)

19/6 + x = 7/15

x = 7/15 - 19/6 = 14/30 - 95/30 = -81/30
