Question

(x+5)+(x-9)=x+2

Answer 1

\(\left(x+5\right)+\left(x-9\right)=x+2\)

= \(x+5+x-9=x+2\)

= \(2x-4=x+2\)

= \(2x-x=2+4\)

\(\rightarrow x=6\)

Answer 2

Ta có: \(\left(x+5\right)+\left(x-9\right)=x+2\)

\(\Rightarrow x+5+x-9-x-2=0\)

\(\Rightarrow x-6=0\)

\(\Rightarrow x=6\)

Vậy: \(x=6\)
