Question

G is in a picture that is 12 inches wide in the middle of a wall that is 29 inches wide how far will the side of the picture be from the edge of the wall

Answer 1

The distance of the side of the picture from the edge of the wall is 8.5 inches

Answer 2

The distance of the side of the picture from the edge of the wall is 8.5 inches

Explanation:

see the attached figure to better understand the problem

Let

x -----> distance of the side of the picture from the edge of the wall

we know that

The wide of the wall must be equal to the wide of the picture plus two times the distance of the side of the picture from the edge of the wall

so

The linear equation that represent this situation is

`2x+12=29`

solve for x

`2x=29-12\\2x=17\\x=8.5\ in`

therefore

The distance of the side of the picture from the edge of the wall is 8.5 inches
