Question

`x+x:5=12,6`

Answer 1

`x+x:5=12,6`

`5xx (x + x : 5) = 12,6 xx 5`

`5x + x = 63`

`6 xx x = 63`

`x=10,5`

Answer 2

\(x+x:5=12,6\)

\(\Rightarrow x\times\left(1+\dfrac{1}{5}\right)=12,6\)

\(\Rightarrow\dfrac{6}{5}\times x=12,6\)

\(\Rightarrow x=12,6:\dfrac{6}{5}\)

\(\Rightarrow x=\dfrac{21}{2}\)

Answer 3

`x + x : 5 = 12,6`

`=> x xx 1 + x xx 1/5 = 12,6`

`=> x xx ( 1 + 1/5)` = 63/5`

`=> x xx 6/5   = 63/5`

`=> x           = 63/5 : 6/5`

`=> x          = 21/2 `
