(580 :4.x-24 ) = 329-150.2.2020
580 :(4.x-24 ) = 329-150.2.2020
(580 :4.x-24 ) = 329-150.2.2020 ( khống đc phép tính nào là số âm cả)
580 :(4.x-24 ) = 329-150.2
580:(x-24)=329-150:2
24 * x -32 * x = 145-225:51
5x + 1 = 625
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
tim x :
a)24.x -32.x =145-255:51
b)580 : ( x -24)=329-150* 21
c) 4x + 4x+1 + 4x+3=1136
a) 580:(x-24)=329-150.21
b)7.(7-14)+35=25+279:9
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
