Question

x : 0,25 - x : 2 = 35

Answer 1

\(x:0,25-x:2=35\)
\(x\times4-x\times\dfrac{1}{2}=35\)
\(x\times\left(4-\dfrac{1}{2}\right)=35\)
\(x\times\dfrac{7}{2}=35\)
\(x=35:\dfrac{7}{2}\)
\(x=10\)

Answer 2

\(x:0,25-x:2=35\)

\(x:\dfrac{1}{4}-x:2=35\)

\(x\times4-x\times\dfrac{1}{2}=35\)

\(x\times\left(4-\dfrac{1}{2}\right)=35\)

\(x\times\dfrac{7}{2}=35\)

\(x=35:\dfrac{7}{2}\)

\(x=10\)

Answer 3

`x:0,25-x:2=35`

`=>x xx 4 -x xx 1/2=35`

`=> x xx (4-1/2)=35`

`=>x xx (8/2-1/2)=35`

`=>x xx 7/2=35`

`=> x=35:7/2`

`=>x=35xx2/7`

`=>x=70/7=10`

Answer 4

\(x:0,25-x:2=35\\ \Rightarrow x\times4-x\times\dfrac{1}{2}=35\\ \Rightarrow x\times\left(4-\dfrac{1}{2}\right)=35\\ \Rightarrow x\times\left(\dfrac{8}{2}-\dfrac{1}{2}\right)=35\\ \Rightarrow x\times\dfrac{7}{2}=35\\ \Rightarrow x=35:\dfrac{7}{2}\\ \Rightarrow x=10\)
