Question

\(\dfrac{x-5}{13}=\dfrac{48}{39}\) ( các bạn nêu từng bước giải nhé:> )

Answer 1

=>(x-5)/13=16/13

=>x-5=16

=>x=21

Answer 2

\(\dfrac{x-5}{13}=\dfrac{48}{39}\)

=>39(x-5)=624

=>x=21

Answer 3

\(\dfrac{x-5}{13}=\dfrac{48}{39}\Leftrightarrow\dfrac{\left(x-5\right)\times3}{13\times3}=\dfrac{48}{39}\Leftrightarrow\dfrac{3x-15}{39}=\dfrac{48}{39}\Leftrightarrow3x-15=48\)

\(\Leftrightarrow3x=63\Leftrightarrow x=21\)
