Answer:
2y = 7
Explanation:
The top rectangle has two pieces in it. Each one is a "y", so there are two y's...that's 2y. That top rectangle is the same size as the bottom rectangle. So the two rectangles are equal. The bottom rectangle is 7.
2y = 7
If you need to continue on and solve it:
2y = 7 Divide both sides by two.
y = 7/2 This is a perfectly good answer. Or y = 3.5
The answer to your question:
2y = 7
