Add (-2X) to both sides: 2X + B + (-2X) = C + (-2X) If we (rearrange) it into B + 2X + (-2X) = C + (-2X) B + 2X - 2X = C + (-2X) Since +2X - 2X = 0 B + 0 = C + (-2X) B = C + (-2X) B = C - 2X
I think it would be 10x12. Because ur basically adding 2 inches to the width. And two inches to the length cuz of the 4 sides of the frame. So in the end the area would be 120 inches squared
