Question

How do you solve `2x-7=6+x`?

Answer 1

`color(green)(x=13`

Explanation:

`color(blue)(2x-7)=color(green)(6+x`

Subtract `color(blue)(x` both sides:

`rarr color(blue)(x-7)=color(green)(6`

`rarrcolor(blue)( x)=color(green)(6+7)`

`rarr color(blue)(x)=color(green)(13`

Check:

Substitute the value of `color(blue)(x` into the equation:

`color(brown)(2(13)-7=6+13`

`color(brown)(26-7=19`

`color(brown)(19=19`

So,the solution is true :)
