Answer 1

Răspuns:

Explicație pas cu pas:

a)

3x/2 = 11/10 - 4/5 = 11/10 - 8/10 = 3/10

x = 3/10 : 3/2 = 3/10 *2/3 = 1/5

b)

4x/7 = 1/2 + 3/14 = 7/14 + 3/14 = 10/14 = 5/7

x = 5/7 : 4/7 = 5/7 * 7/4 = 5/4

c)

5x/6 = 3/2 - 1/3 = 9/6 - 2/6 = 7/6

x = 7/6 : 5/6 = 7/6 *6/5 = 7/5

d)

2x/5 = 22/15 - 4/3 = 22/15 - 20/15 = 2/15

x = 2/15 : 2/5 = 2/15 *5/2 = 1/3

e)

2x/3 = 4/8 - 11/24 = 12/24 - 11/24 = 1/24

x = 1/24 : 2/3 = 1/24*3/2 = 1/16

f)

5x/12 = 7/6 + 3/8 = 28/24 + 9/24 = 37/24

x = 37/24 : 5/12 = 37/24*12/5 = 37/10
