( 3x - 24 ) x73 = 3 x 73
mình đang cần gấp
3x+2 - 3x = 72
24-x = 72
(3x – 24 ).73= 2.74
71-(24-3x)=23
71-(24-3x)=23
TTìm số nguyên x, biết: a) 262 + ( 2x - 123)= 283; b) 63 - ( - 51 + 3x) = 237 c) - ( 2x + 24) + 211 = -123 d) 125 - ( 125 - x) + 22+ 3x) = 237 c) - ( 2x + 24) + 211 = -123 d) 125 - ( 125 - x) + 22
giúp emmmmm
l) (3x – 6) .3 = 34
m) (5x – 24) .38 = 2.311
n) 3x = 9
p) 4x = 64
q) 2x = 16
(3x+1).5=36-24
Tính:
(3x-24).7326=22.7327
