Ta có: \(f\left(x\right)=g\left(x\right)\Leftrightarrow x-1010=2x-1020\Leftrightarrow x=10\)
Vậy....................
\(f\left(x\right)=x-1010\)
\(g\left(x\right)=2x-1020\)
Để \(f\left(x\right)=g\left(x\right).\)
\(\Rightarrow x-1010=2x-1020\)
\(\Rightarrow x-2x=\left(-1020\right)+1010\)
\(\Rightarrow-1x=-10\)
\(\Rightarrow x=10:1\)
\(\Rightarrow x=10\)
Vậy \(x=10\) thì \(f\left(x\right)=g\left(x\right).\)
Chúc bạn học tốt!
