Question

Tìm x: d) 816-2(x+3)=106 giải em câu cuối này ạ

Answer 1

\(2\left(x+3\right)=816-106\\ 2\left(x+3\right)=710\\ x+3=355\\ x=355-3\\ x=352\)

Answer 2

`816-2(x+3)=106`

`=> 2(x+3)=816-106`

`=> 2(x+3)= 710`

`=>x+3=710:2`

`=>x+3=355`

`=>x=355-3`

`=>x=352`

Answer 3

`816-2.(x+3)=106`

`2.(x+3)=816-106`

`2.(x+3)=710`

`2x+6=710`

`2x=710-6`

`2x=704`

`x=704:2`

`x=352`

Vậy `x=352`
