Question

\(\dfrac{x+3}{2}=\dfrac{x-3}{5}\)

Answer 1

\(\dfrac{x+3}{2}=\dfrac{x-3}{5}\)

\(\Rightarrow5\left(x+3\right)=2\left(x-3\right)\)

\(\Rightarrow5x+15=2x-6\)

\(\Rightarrow5x-2x=-15-6\)

\(\Rightarrow3x=-21\)

\(\Rightarrow x=-7.\)

Answer 2

Ta có : \(\dfrac{x+3}{2}=\dfrac{x-3}{5}\)

\(\Leftrightarrow5\left(x+3\right)=2\left(x-3\right)\)

\(\Leftrightarrow5x+15=2x-6\)

\(\Leftrightarrow3x=-21\Leftrightarrow x=-7\)

Vậy x = -7.

tik mik nha !!!

Answer 3

\(\dfrac{x+3}{2}=\dfrac{x-3}{5}\)

\(\Rightarrow5\left(x+3\right)=2\left(x-3\right)\)

\(\Rightarrow5x+15=2x-6\)

\(\Rightarrow5x+15+6=2x\)

\(\Rightarrow5x+21=2x\)

\(\Rightarrow-3x=21\)

\(\Rightarrow x=-7\)
