Question

Tìm x biết :

/ x- 6 / + 2x = 10

Answer 1

=>/x-6/=10-2x

=>\(\orbr{\begin{cases}x-6==10-2x\\x-6=-10+2x\end{cases}}\)
th1: x-6=10-2x

  =>x+2x=10+6

 =>3x=16

 =>x=\(\frac{16}{3}\)

th2:x-6=-10+2x

 =>x-2x=-10+6

 =>-1x=-4

 =>x=4

   =>\(\orbr{\begin{cases}x=\frac{10}{3}\\x=4\end{cases}}\)
