Question

Answer 1

x - 7/18 = -12/29 : 18/29

x - 7/18 = -2/3

x =-2/3 + 7/18

x  = -5/18

Answer 2

\(\Leftrightarrow x-\dfrac{7}{18}=-\dfrac{12}{29}:\dfrac{18}{29}\)

\(\Leftrightarrow x-\dfrac{7}{18}=-\dfrac{12}{29}\times\dfrac{29}{18}\)

\(\Leftrightarrow x-\dfrac{7}{18}=-\dfrac{2}{3}\)

\(\Leftrightarrow x=-\dfrac{2}{3}+\dfrac{7}{18}\)

\(\Leftrightarrow x=-\dfrac{12}{18}+\dfrac{7}{18}\)

\(\Leftrightarrow x=-\dfrac{5}{18}\)

Answer 3

(x - 7/18).18/29=-12/29

(x - 7/18)          =-12/29 : 18/29

(x - 7/18)          =-12/29 . 29/18

(x - 7/18)          =-2/3

x                       = 2/3 + 7/18

x                       = -5/18

Answer 4

\(\left(x-\dfrac{7}{18}\right).\dfrac{18}{29}=-\dfrac{12}{29}\)

\(\left(x-\dfrac{7}{18}\right)\)        \(=\left(-\dfrac{12}{29}\right):\dfrac{18}{29}=-\dfrac{2}{3}\)

  \(x\)                      \(=-\dfrac{2}{3}+\dfrac{7}{18}=-\dfrac{5}{18}\)
