580:(x-24)=329-150:2
=> 580:(x-24)=329-75
=> 580:(x-24)=254
=>x-24= 580:254
=> x = 290/127 + 24
=> x = 3338/127
+) 24 * x -32 * x = 145-225:51
=> x.(24 -32) = 145-225:51
=> x.7= 145-225:51
=> x.7= 2390/17
=> x= 2390/119
+) 5x + 1 = 625
=> 5x + 1 = 54
=> x+1 = 4
=> x = 3
tim x :
a)24.x -32.x =145-255:51
b)580 : ( x -24)=329-150* 21
c) 4x + 4x+1 + 4x+3=1136
Bài 1: Tìm x, biết:
a) 24 . x - 32 . x = 145 - 255 / 51
b) 580 / ( x - 24 ) = 329 - 150 . 2
c) 7. ( x - 14 ) + 35 = 25 + 279 / 9
thanks
Tìm x :
a)\(2^4.x-3^2.x=145-255:51\)
b)\(580:\left(x-24\right)=329-150.2^1\)
c)\(7.\left(x-14\right)+35=25+279:9\)
Giá trị nào dưới đây của x thỏa mãn 2 4 . x - 3 2 . x =145-225:51?
A. 20
B. 30
C. 40
D. 80
a)4*x+79*29=79*33
b)83-3*(7+x)=64
c)(x-7)*(2*x-8)=0
d)580:(x-24)=329-150:2
580 :(4.x-24 ) = 329-150.2.2020
580 :(4.x-24 ) = 329-150.2
(580 :4.x-24 ) = 329-150.2.2020
580 :(4.x-24 ) = 329-150.2.2020
