Question

tìm x \(\dfrac{6}{x}\)=\(\dfrac{24}{x-27}\)

Answer 1

\(\dfrac{6}{x}=\dfrac{24}{x-27}\)

Theo định nghĩa phân số bằng nhau, ta có:

\(6\cdot\left(x-27\right)=24x\\ 6x-162=24x\\ -162=24x-6x\\ -162=18x\\ x=\left(-162\right):18\\ x=-9\)

Answer 2

Theo bài ra ta có:

6.(x-27)=x.24

6x-162=x.24

-162=24x-6x

-162=18x

x =(-162):18

x = -9

tick mk nha
