( x - 1) : $\frac{1}{2}$ = $\frac{1}{2}$ + $1\frac{1}{2}$

Nguyễn Hưng Phát · Accepted Answer

$\left(x-1\right):\frac{1}{2}=\frac{1}{2}+1\frac{1}{2}$$\Rightarrow\left(x-1\right).2=1+1$$\Rightarrow\left(x-1\right).2=2$$\Rightarrow\left(x-1\right)=2:2$$\Rightarrow x-1=1$$\Rightarrow x=1+1$$\Rightarrow x=2$Câu trả lời: $\left(x-1\right):\frac{1}{2}=\frac{1}{2}+1\frac{1}{2}$$\Rightarrow\left(x-1\right).2=1+1$$\Rightarrow\left(x-1\right).2=2$$\Rightarrow\left(x-1\right)=2:2$$\Rightarrow x-1=1$$\Rightarrow x=1+1$$\Rightarrow x=2$
