Question

\(\dfrac{-12}{13}\)x-5=\(6\dfrac{1}{13}\)

Answer 1

\(\dfrac{-12}{13}\)X-5=6\(\dfrac{1}{13}\)

\(\dfrac{-12}{13}\)X-5=\(\dfrac{79}{13}\)

X-5=\(\dfrac{79}{13}\): \(\dfrac{-12}{13}\)

X-5=\(\dfrac{79}{13}\)x\(\dfrac{-13}{12}\)

X-5=\(\dfrac{-1027}{156}\)

X-5=\(\dfrac{-79}{12}\)

X =\(\dfrac{-79}{12}\)+5

X =\(\dfrac{-79}{12}\)+\(\dfrac{60}{12}\)

X = \(\dfrac{-19}{12}\)

X = -1\(\dfrac{7}{12}\)

Mình giải rõ ràng vì sợ bạn không hiểu nên hơi dài bạn thông cảm nha.

Answer 2

= -12/13x-5 = 79/13

=-12/13x=79/13+5

=-12/13x=144/13

x= 144/13 : -12/13

x= 144/13 . ( -13/12 )

x= -12

Vậy x=-12

Answer 3

\(\dfrac{-12}{13}\)x-5=6\(\dfrac{1}{13}\)

x-5=\(\dfrac{79}{13}\)x\(\dfrac{13}{-12}\)

x-5=\(\dfrac{79}{-12}\)

x=\(\dfrac{79}{-12}\)+\(\dfrac{-60}{-12}\)

x=\(\dfrac{19}{-12}\)
