Question

7. Rezolvați ecuațiile:
a) x + 31 = 125
b) 2x - 7 = 11
c) 78 - X= 45
d) 2 (x - 7) = 44
e) 96: x= 16
f)x: 8= 11​

Answer 1

Răspuns:

a)x + 31 = 125

x=125-31

x=96

b)2x - 7 =11

11-7=4

x=4

d)78-X=45

X=78-45

X=33

e)96:x=16

x=96:16

x=6

f)x:8=11

x=11×8

x=88

Answer 2

Răspuns:

a) x+31=125

x=125-31

x=94

b) 2x+7=11

2x=11-7

2x=4

x=4÷2

x=2

c)78-x=44

x=78-44

×=34

d)2(x-7)=44

x-7=44÷2

x-7=22

x=22+7

x=29

e) 96÷x=16

x=96:16

x=6

f)x÷8=11

x=11×8

x=88
