Question

X-2 /5 = 5-x/ 15

Answer 1

\(\dfrac{x-2}{5}=\dfrac{5-x}{15}\)

\(\Leftrightarrow15\cdot\left(x-2\right)=5\cdot\left(5-x\right)\)

\(\Leftrightarrow15x-30-25+5x=0\)

\(\Leftrightarrow20x-55=0\)

\(\Leftrightarrow x=\dfrac{55}{20}=\dfrac{11}{4}\)

Answer 2

x-2/5=5-x/15

⇒15.(x-2)=5.(5-x)

    15x-30=25-5x

   15x+5x=25+30

         20x=55

             x=55:20

             x=11/4
