Question

tìm các số tự nhiên xy sao cho x-3=y.(x+2)

Answer 1

x−3=y.(x+2)

⇒(x+2)−5=y.(x+2)

⇒(x+2)−5−y.(x+2)=0

⇒(x+2).(1−y)=5

Answer 2

\(x-3=y.\left(x+2\right)\)

\(\Rightarrow\left(x+2\right)-5=y.\left(x+2\right)\)

\(\Rightarrow\left(x+2\right)-5-y.\left(x+2\right)=0\)

\(\Rightarrow\left(x+2\right).\left(1-y\right)=5\)
