Question

Tìm x: \(60\%x+\dfrac{2}{3}x=-76\)

Answer 1

\(60\%x+\dfrac{2}{3}x=-76\)

\(\dfrac{3}{5}x+\dfrac{2}{3}x=-76\)

\(x\left(\dfrac{3}{5}+\dfrac{2}{3}\right)=-76\)

\(x\dfrac{19}{15}=-76\)

\(x=-76:\dfrac{19}{15}\)

\(x=-60\)

Answer 2

\(60\%x+\dfrac{2}{3}x=-76\)

\(\dfrac{3}{5}x+\dfrac{2}{3}x=-76\)

\(x.\left(\dfrac{3}{5}+\dfrac{2}{3}\right)=-76\)

\(x.\dfrac{19}{15}=-76\)

\(x=-76:\dfrac{19}{15}\)

\(x=-76.\dfrac{15}{19}\)

\(x=-60\)

Answer 3

`60% x+2/3x=-76`

`3/5x+2/3x=-76`

`(3/5+2/3)x=-76`

`19/15x=-76`

`x=-76:19/15`

`x=-60`
