Question

Answer 1

=>3x=15,6

=>x=5,2

Answer 2

`x:0,15-x=15,6`

`=>x xx 4 - x=15,6`

`=> x xx(4-1)=15,6`

`=> x xx3=15,6`

`=> x=15,6:3`

`=>x=5,2`

Answer 3

\(x:0,25-x=15,6\\ \Leftrightarrow x:\dfrac{1}{4}-x=15,6\\ \Leftrightarrow4x-x=15,6\\ \Leftrightarrow3x=15,6\\ \Leftrightarrow x=15,6:3\\ \Leftrightarrow x=5,2\)

Answer 4

\(x:0,25-x=15,6\)

\(x.4-x.1=15,6\)

\(x.3=15,6\)

\(x=15,6:3\)

\(x=5,2\)

Answer 5

Answer 6

x:0,25−x=15,6

⇔x:1/4−x=15,6

⇔3x=15,6

⇔x=5,2
