Question

3n - 2 = n - 5
Tính n
 

Answer 1

3n - 2 = n - 5

3n - 2 - n = -5

2n - 2 = -5

2n = -5 + 2

2n = -3

n = -3 : 2

n = -6

Answer 2

\(3n-2=n-5\)

\(3n-n=-5+2\)

\(2n=-3\)

\(n=-\frac{3}{2}\)

Answer 3

Ta có: \(3n-2=n-5\)

\(\Rightarrow3n-n=2-5\)

\(\Rightarrow2n=-3\)

\(\Rightarrow n=\frac{-3}{2}\)

Vậy \(n=\frac{-3}{2}\)

Answer 4

3n - 2 = n - 5

3n - 2 - n = -5

2n - 2 = - 5

2n = -5 + 2

2n = -3 

n = -3 . 2 

n = -6
