Question

7/5+8/5.(x+1)=3 

Cần câu trả gấp ạ

Answer 1

7/5 + 8/5( x+1)= 3

         8/5(x+1) = 3 - 7/5

         8/5(x+1) = 8/5

           x+1 = 8/5:8/5

           x+1 = 1

    => x = 1-1 = 0

Vậy x = 0

            

Answer 2

x=0

Answer 3

\(\dfrac{7}{5}+\dfrac{8}{5}.\left(x+1\right)=3\\ \dfrac{8}{5}.\left(x+1\right)=3-\dfrac{7}{5}=\dfrac{8}{5}.\left(x+1\right)=\dfrac{8}{5}\\ x+1=\dfrac{8}{5}:\dfrac{8}{5}\\ x+1=1\\ \Rightarrow x=0\)
