Let's call the width of the border "x". The total width of the photo and the frame is 7 inches, so the width of the photo (4 inches) plus the width of the border equals 7 inches.
Therefore, the equation to model the situation is: 4 + x = 7.
To solve the equation for the width of the border, let's isolate "x" by subtracting 4 from both sides of the equation:
4 + x - 4 = 7 - 4.
This simplifies to:
x = 3.
Therefore, the width of the border is 3 inches.
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...
