Question

Rezolvati urmatoarea ecuatie in Q

Answer 1

1/7(x - 23/10) = 5/14
1/7(10x/10 - 23/10) = 5/14
10x/70 - 23/70 = 5/14    - aducem la acelasi numitor ... 70 ....si eliminam numitorul prin inmultire cu el insusi
10x/70 - 23/70 = 25/70
10x - 23 = 25
10x = 25 + 23
10x = 48
x= 48/10= simplificam cu 2 = 24/5
x= 4,8

Answer 2

1/7(x - 2.3) = 5/14

x/7 - 2.3/7 = 5/14

2x - 4.6 = 5

2x = 9.6

x = 4.8
