A photo is 4 inches wide. It is placed inside a frame with a border that is x inches wide. The total width of the photo and the frame is 7 inches. Write an equation to model the situation. Then solve the equation to find the width of the border.

Question

4 + x = 7
x = 7 - 4
x = 3

Is this what they want?

Answer 1

That's a good start, but there is border on both sides of the photo.

Answer 2

Oh ok, so it would be 2x, not just x

Answer 3

So:
4 + 2x = 7
2x = 7 - 4
2x = 3
x = 3/2
Is this correct?

Answer 4

yes
