Answer:

An equation to model the situation is 18+2x=24 and the width of the border is 3 inches

Step-by-step explanation:

Given :A painting is 18 inches wide. It is placed inside a frame with a border that is x inches wide.

The total width of the painting and the frame is 24 inches.

To Find : Create an equation to model the situation, and then solve the equation to find the width of the border.

Width of painting = 18 inches

It is placed inside a frame with a border that is x inches wide. (from 1 side)

So, Total width of painting +frame  = 18+2x

We are given that The total width of the painting and the frame is 24 inches.

2x=6

x=3

Hence an equation to model the situation is 18+2x=24 and the width of the border is 3 inches
