Answer 1

4+5x=29 5x=29-5 5x=24 /:5 x=24/5= 4 4/5 7-x=22 -x=22-7 -x=15 /:(-1) x=-15 1/3x-4=2 1/3x=2+4 1/3x=6 /:1/3 x=6:1/3=6×3=18

Answer 2

4 + 5x = 29

5x = 29 - 4

5x= 25

x= 25 : 5

x= 5


spr.
4 + 5x = 29

L= 4 + 5x= 4 + 5 * 5= 4 + 25 = 29

P = 29

L = P




7 - x= 22

- x= 22 - 7

-x = 15  /*(-1)

x= - 15


spr.

7 - x= 22

L= 7 - x= 7 - (-15) = 7 + 15 = 22

P = 22

L=P



1/3x - 4 = 2

1/3x= 2 + 4

1/3x= 6

x= 6 : 1/3

x= 6 * 3/1

x= 18/1

x= 18


spr

1/3x - 4= 2

L = 1/3x - 4= 1/3 * 18 - 4= 1/1 * 6 - 4= 6/1 - 4= 6-4= 2

P=2

L=P
