Question

Tìm x:
5 . x + 8 - x =36

Answer 1

`5.x +8-x =36`

` x(5-1) =36 -8`

`4*x = 28`

`x=28/4 =7`

Vậy `x=7`

Answer 2

\(\Leftrightarrow5x-x+8=36\)

\(\Leftrightarrow4x+8=36\)

\(\Leftrightarrow4x=36-8\)

\(\Leftrightarrow4x=28\)

\(\Rightarrow x=\dfrac{28}{4}=7\)

Answer 3

\(5.x+8-x=36\)

\(4x+8=36\)

\(4x=36-8\)

\(4x=28\)

\(x=\dfrac{28}{4}\)

\(\Rightarrow x=7\)
