Answer 1

đề em đánh lỗi mg thông cảm ạ

Answer 2

\(\dfrac{-7}{1+2x}=\dfrac{5}{2-3x}\left(đk:x\ne-\dfrac{1}{2},x\ne\dfrac{2}{3}\right)\)

\(\Rightarrow\left(-7\right)\left(2-3x\right)=5\left(1+2x\right)\)

\(\Rightarrow21x-14=5+10x\)

\(\Rightarrow11x=19\Rightarrow x=\dfrac{19}{11}\left(tm\right)\)
