Question

tìm x

x/10=-3/5

x+5/12=-2/3

Answer 1

\(\dfrac{x}{10}=\dfrac{-3}{5}\\ \Rightarrow x=\dfrac{10.\left(-3\right)}{5}=-6\\ ------------\\ x+\dfrac{5}{12}=\dfrac{-2}{3}\\ x=\dfrac{-2}{3}-\dfrac{5}{12}\\ x=\dfrac{-8}{12}-\dfrac{5}{12}\\ x=\dfrac{-13}{12}\)

Answer 2

`x`=`-6`

`x` = `-13/12`

Answer 3

x/10=-3/5

x/10=-3.2/5.2

x/10=-6/10

x=-6

x+5/12=-2/3

x=-2/3-5/12

x=8/12-5/12

x=3/12

x=1/4
