Answer 2

`10x-3\left(x-7\right)=x+39`

`-3\left(x-7\right)`

`-3x+21`

`10x-3x+21=x+39`

** Combine like terms ↓ **

`10x-3x=7x`

** Subtract 21 from both sides ↓**

`7x+21-21=x+39-21`

`7x=x+18`

** Subtract x from both sides ↓ **

`7x-x=x+18-x`

`6x=18`

**Divide both sides by 6 ↓*

`\cfrac{6x}{6}=\cfrac{18}{6}`

`x=3`
