Question

2 x (1/4 - 3x) = 1/5 - 4x

ai biết giải hộ mk với

Answer 1

2 x (1/4 - 3x) = 1/5 - 4x

=> 1/2 . 6x = 1/5 - 4x

=> 1/2 - 1/5 = 6x - 4x

=> 3/10 = 2x

=> x = 3/20

tiick mk nha

Answer 2

2 \(\times\) (1/4 - 3x) = 1/5 - 4x

-> (2\(\times\) 1/4) - (2 \(\times\) 3x) = 1/5 - 4x

-> 1/2 - 6x = 1/5 - 4x

->1/2 - 6x - 1/5 + 4x = 0

->3/10 - 2x = 0

->2x = 3/10

->x = 3/20

Vậy....
