Tìm x,y
a) x/2=y/3 và xy+=24
b) 4x+5/10x+2=2x+3/5x+2
Tìm x biết :2x+3/5x+2 = 4x+5/10x+2
2x+3/5x+2=4x+5/10x+2.Tìm x
Tìm x biết: 2x+3/5x+2=4x+5/10x+2
Tìm x biết :2x+3/5x+2 = 4x+5/10x+2
tìm x : biết
(2x+3)/(5x+2)=(4x+5)/(10x+2)
tìm x biết:
2x+3/5x+2= 4x+5/10x+2
: Tìm x, biết:
a) 3x( 4x- 1) - 2x(6x- 3 )=30 b) 2x(3-2x) + 2x(2x-1)=15
c) (5x-2)(4x-1) + (10x +3)(2x - 1)=1 d) (x+2) (x+2)- (x -3)(x+1) = 9
e) (4x+1)(6x-3) = 7 + (3x – 2)(8x + 9) g) (10x+2)(4x- 1)- (8x -3)(5x+2) =14
Gía trị của x thoải mãn 2x+3/5x+2 = 4x+5/10x+2
