k mik nha

Answer 3

x=6.7:(-4)=?

Answer 4

\(-\frac{4}{7}=\frac{6}{x}\)        ĐK: x khác 0

\(\Rightarrow x=\left(6\cdot7\right):\left(-4\right)\)

\(\Rightarrow x=42:\left(-4\right)\)

\(\Rightarrow x=-10,5\)

vậy x=-10,5

Answer 5

\(\frac{-4}{7}=\frac{6}{x}\)

\(\Rightarrow(-4)x=6.7\)

\(\Rightarrow-4.x=42\)

\(\Rightarrow x=42\div(-4)\)

\(\Rightarrow x\in\varnothing\)
