60%x + 2/3.x = -7/6
<=> 3/5x + 2/3x = (-7/6)
=> ( 3/5 + 2/3) x = (-7/6)
=> 19/15x = (-7/6)
=> x = (-7/6) : 19/15
=> x = -38/35
\(60\%x+\frac{2}{3}\cdot x=-\frac{7}{6}\)
\(=x\left(60\%+\frac{2}{3}\right)=-\frac{7}{6}\)
\(\Rightarrow x\cdot\frac{19}{15}=-\frac{7}{6}\)
\(\Rightarrow x=-\frac{7}{6}:\frac{19}{15}\)
\(\Rightarrow x=-\frac{35}{38}\)
