Question

5nhân mở ngoặc vuông 225-(x-10) đóng ngoặc vuông-125=0

Answer 1

`5. [225-(x-10) ]-125=0`

`5. [225-(x-10) ]=125`

`225-(x-10) = 125:5`

`225-(x-10) =25`

`x-10=225-25`

`x-10=200`

`x=210`

Answer 2

\(5\times\left[225-\left(x-10\right)\right]-125=0\)

\(\Rightarrow\)\(5\times\left[225-\left(x-10\right)\right]=125\)

`=>`\(225-\left(x-10\right)=25\)

`=>`\(x-10=225-25=200\)

`=>x=210`
