Question

5/x-2=10/16

Answer 1

`5/[x-2]=10/16`

`10(x-2)=16.5=80`

`x-2=80:10=8`

`x=8+2=10`

Answer 2

\(\dfrac{5}{x-2}=\dfrac{10}{16}\)

\(\Rightarrow5.16=\left(x-2\right).10\)

\(\Rightarrow\left(x-2\right).10=80\)

\(\Rightarrow x-2=80:10\)

\(\Rightarrow x-2=8\)

\(\Rightarrow x=8+2\)

\(\Rightarrow x=10\)

 

Answer 3

\(\dfrac{5}{x-2}=\dfrac{10}{16}\) 

\(\Leftrightarrow5\cdot16=\left(x-2\right)\cdot10\) 
\(\Leftrightarrow80=10x-20\) 
\(\Leftrightarrow10x=20+80\) 
\(\Leftrightarrow10x=100\) 
\(\Leftrightarrow x=\dfrac{100}{10}=10\)
