Explicație pas cu pas:

4.

(y : 3) : 4 = 2

y : 3 = 2×4

y : 3 = 8

y = 8×3

y = 24

_______________

18 : ( y ×2) = 3

y × 2 = 18 : 3

y × 2 = 6

y = 6 : 2

y = 3

_______________

28 : ( y+6) = 4

y + 6 = 28 : 4

y + 6 = 7

y = 7 - 6

y = 1

________________

36 : ( y + 1 ) = 4

y + 1 = 36 : 4

y + 1 = 9

y = 9 - 1

y = 8

____________________

( y+2) : 4 = 5

y + 2 = 5 × 4

y + 2 = 20

y = 20 - 2

y = 18

_______________

8 × ( 3 : a ) = 24

3 : a = 24 : 8

3 : a = 3

a = 3 : 3

a = 1
