Theo đề bài ta có: \(2x=3y\Rightarrow\dfrac{x}{3}=\dfrac{y}{2}\)và x + y = 180^o (2 góc trong cùng phía)

Áp dụng dãy tỉ số bằng nhau ta có:

 \(\dfrac{x}{3}=\dfrac{y}{2}=\dfrac{x+y}{3+2}=\dfrac{180^o}{5}=36^o\)

\(\Rightarrow\left\{{}\begin{matrix}x=36^o.3=108^o\\y=36^o.2=72^o\end{matrix}\right.\)

(x + 1)² = x + 1

⇒ (x + 1)² - (x + 1)=  0

⇒ (x + 1) . (x + 1 - 1) =0

⇒  (x + 1) . x = 0

\(\Rightarrow\left[{}\begin{matrix}x+1=0\\x=0\end{matrix}\right.\Rightarrow\left[{}\begin{matrix}x=-1\\x=0\end{matrix}\right.\)

Miss Trang is taller than her sisiter

The market is noisier than street

The boys are weaker than the girl
