44 + ( 16 - x ) = 50
=> 16 - x = 50 - 44
=>16 - x = 6
=> x = 16 - 6
=> x = 10
tíc mình nha
a / ( 16 - x ) = 50 - 40
16 - x = 10
x = 16 - 10
x= 6
b/ ( 7x + 60 ) = 585 - 455
7x + 60 = 130
7x = 130 - 60
7x = 70
x= 70 chia 7
x= 10
c/ minh ko bit
a ) 44 + ( 16 - x ) = 50
16 - x = 50 - 44
16 - x = 6
x = 16 - 6
x = 10
b) 585 - ( 7x + 60 ) = 455
7x + 60 = 585 - 455
7x + 60 = 130
7x = 130 - 60
7x = 70
x = 70 : 7
x = 10
c ) 22x : 22 = 10 . 24 - 6 . 24
22x : 4 = 10 . 16 - 6 . 16
22x : 4 = 160 - 96
22x : 4 = 64
22x = 64 x 4
22x = 256
x = 256 : 22
x = 11,6363
