Question

Tìm x:

X-1,5 =2x/3

 

Answer 1

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

\(x=\frac{2x}{3}+1,5\)

\(\frac{3x}{3}=\frac{2x}{3}+\frac{4,5}{3}\)

\(\frac{3x}{3}=\frac{2x+4,5}{3}\)

\(3x=2x+4.5\)

\(3x-2x=4.5\)

 \(x=4,5\)

Vây x = 4,5

Answer 2

\(\chi-\frac{3}{2}=\frac{2}{3}x\)

\(\chi-\frac{2}{3}x=\frac{3}{2}\)

\(-\frac{1}{3}x=\frac{3}{2}\)

\(\chi=-\frac{9}{2}\)
