Question

3 ( x+1 ) =x + 6

Answer 1

Ta có: 3(x+1)=x+6

\(\Leftrightarrow3x+3-x-6=0\)

\(\Leftrightarrow2x-3=0\)

\(\Leftrightarrow2x=3\)

hay \(x=\dfrac{3}{2}\)

Vậy: \(x=\dfrac{3}{2}\)

Answer 2

3(\(x\)+1)=x+6

⇒3\(x\)+3=\(x\)+6

⇒3\(x\)+3-\(x\)+6=0

⇒2\(x\)-3=0

⇒2\(x\)=3

     \(x\)=\(\dfrac{3}{2}\)

vậy \(x=\dfrac{3}{2}\)
