a) 2x - ( 40 - 52 ) = x + 12
2x - 40 + 52 = x + 12
x = 0
b) 40 - x =-12 + 3x
4x = 52
x = 13
a) 2x - ( 40 - 52 ) = x + 12
2x - 40 + 52 = x + 12
x = 0
b) 40 - x =-12 + 3x
4x = 52
x = 13
tìm x(=quy tắc chuyển vế)
a) 2x-(40-52)=x+12
b) 40-x=-12+3x
giúp mik với,tks
Tìm x:
38 - x.12 - x.16 = 40
Giúp mik vs
B1/Tìm x:
a/ 2x-16=40+x
b/ 16-2x=40-3x
c/ 6(x-1)-5x=15
giải hộ mik nha
tính nhanh [(40/130 - 12/13 )x 40% + 0,15 ]chia -5/52

Tìm x,y thuộc:
|x - 40| + |x -y +10| =0
GIÚP mik vs mn ơi
