Salut!

a)36:9x y= 28

4x y=28

y=7

b) (x:8)+18=21

x:8=3

x=3x8=24

c) (32:w)-6=2

32:w=8

w=4

Succes!

Answer 2

❁ 2

a) 36 : 9 × y = 28

4 × y = 28

y = 28 : 4

y = 7

b) ( z : 8 ) + 18 = 7 × 3

( z : 8 ) + 18 = 21

z : 8 = 21 - 18

z : 8 = 3

z = 8 × 3

z = 24

c) ( 32 : w ) - 6 = 12 : 6

( 32 : w ) - 6 = 2

32 : w = 6 + 2

32 : w = 8

w = 32 : 8

w = 4
