Question

How do you solve `2( s - 7) = 2`?

Answer 1

`s=8`

Explanation:

`"divide both sides by 2"`

`cancel(2)/cancel(2)(s-7)=2/2`

`rArrs-7=1`

`"add 7 to both sides"`

`scancel(-7)cancel(+7)=1+7`

`rArrs=8" is the solution"`

Answer 2

See a solution process below:

Explanation:

First, divide each side of the equation by `color(red)(2)` to eliminate the need for parenthesis while keeping the equation balanced:

`(2(s - 7))/color(red)(2) = 2/color(red)(2)`

`(color(red)(cancel(color(black)(2)))(s - 7))/cancel(color(red)(2)) = 1`

`s - 7 = 1`

Now, add `color(red)(7)` to each side of the equation to solve for `s` while keeping the equation balanced:

`s - 7 + color(red)(7) = 1 + color(red)(7)`

`s - 0 = 8`

`s = 8`
