Bonsoir;

a-11=35

a =35+11

a = 46

x+35 = 60

x= 60-35

x= 25

4x = 84

x = 84/4

x= 21

56/a = 8

56 = 8a

a = 56/8

a = 7

2m+ 6 = 25

2m = 25-6

2m = 19

m = 19/2

m = 9,5

5a-20 =-25

5a = -25+20

5a = -5

a = -5/5

a = -1

-3x + 13 = -14

13+14 = 3x

27 =3x

x = 27/3

x = 9

14-4b = -28

14+28 = 4b

42=4b

b = 42/4

b = 10,5

35a-10 = 15a + 16

35a -15a = 16+10

20a = 26

a = 26/20

a = 13/10

a = 1,3

2(x+1)+5=10-(x-3)

2x+2 +5 = 10-x+3

2x+x = 10+3 -2 -5

3x = 6

x = 6/3

x = 2
