Question

0.24 . ( x + 7/10 ) = -2,4

Answer 1

\(0,24.\left(x+\dfrac{7}{10}\right)=-2,4\)

\(\dfrac{24}{100}.\left(x+\dfrac{7}{10}\right)=-\dfrac{24}{10}\)

\(\dfrac{6}{25}.\left(x+\dfrac{7}{10}\right)=-\dfrac{12}{5}\)

\(x+\dfrac{7}{10}=-\dfrac{12}{5}:\dfrac{6}{25}\)

\(x+\dfrac{7}{10}=-\dfrac{12}{5}.\dfrac{25}{6}\)

\(x+\dfrac{7}{10}=-10\)

\(x=-10-\dfrac{7}{10}\)

\(x=-\dfrac{107}{10}\)

Answer 2

x+7/10=-24/10:24/100
x+7/10=-10
x=-10-7/10
x=-107/10
