Question

x-1,5=2x/3

Answer 1

\(x-1.5=\dfrac{2}{3}x\)

=>\(x-\dfrac{2}{3}x=1.5=\dfrac{3}{2}\)

=>\(\dfrac{1}{3}x=\dfrac{3}{2}\)

=>\(x=\dfrac{3}{2}\cdot3=\dfrac{9}{2}\)

Answer 2

\(x-1,5=\dfrac{2x}{3}\)

\(\Rightarrow\dfrac{3\left(x-1,5\right)}{3}=\dfrac{2x}{3}\)

\(\Rightarrow3\left(x-1,5\right)=2x\)

\(\Rightarrow3x-4,5=2x\)

\(\Rightarrow3x-2x=4,5\)

\(\Rightarrow x=4,5\)

Vậy: \(x=4,5\)
