b2 Tìm x

1,5.x-7/3.x=1,5-2/3

Answer 1

Làm:

\(1,5\cdot x-\frac{7}{3}x=1,5-\frac{2}{3}\)

\(\left(1,5-\frac{7}{3}\right)x=\frac{5}{6}\)

\(\Leftrightarrow\)    \(-\frac{5}{6}x=\frac{5}{6}\)

\(\Leftrightarrow\)              \(x=-1\)

Answer 2

    1,5 . x - 7/3 . x = 1,5 - 2/3

=> 1,5 . x - 7/3 . x = 5/6

=>1,5 . x = 5/6 - 7/3

=> 1,5 . x = - 3/2

=> x = - 3/2 : 1,5

=> x = -1

Vay x = - 1
