Answer 1

Răspuns:

a) 4z - 6 = 194

4z = 194 + 6

4z = 200

z = 200 : 4

z = 50

b) 35 + 5a = 95

5a = 95 - 35

5a = 60

a = 60 : 5

a = 12

c) 8b + 26 = 58

8b = 58 - 26

8b = 32

b = 32 : 8

b = 4

d) 3( 2 + x ) = 9

6 + 3x = 9

3x = 9 - 6

3x = 3

x = 3 : 3

x = 1

e) ( 15 - x ) : 3 = 5

15 - x = 5 • 3

15 - x = 15

x = 15 - 15

x = 0

f) 42 : ( y + 4 ) = 6

42 : 6 = y + 4

7 = y + 4

y = 7 - 4

y = 3

a) 4z - z = 24 + 5 • 12

3z = 24 + 60

3z = 84

z = 84 : 3

z = 28
