tìm x

3 . (x - 5) - 2 . (x - 1) = 3

Answer 1

3.(x-5)-2.(x-1) = 3

=> 3x-(-15) - 2x -2 = 3

=> 3x-2x = 3+2+15

=> x = 20

Answer 2

<=> 3x-15-2x-2=3

<=> 3x-2x = 3+15+2

<=> x = 20

Answer 3

\(3\left(x-5\right)-2\left(x-1\right)=3\)

\(\Rightarrow3x-15-2x+2=3\)

\(\Rightarrow x=3+15-2\)

\(\Rightarrow x=16\)

Vậy x = 16

Answer 4

\(3\left(x-5\right)-2\left(x-1\right)=3\)

\(\Leftrightarrow3x-15-2x+2=3\)

\(\Leftrightarrow x-13=3\)

\(\Leftrightarrow x=16\)

Vậy phương trình có nghiệm x = 16 .
