First of all, we're learning how to solve equations with variables on both sides.
Write and solve an equation for the situation.
An architect is designing a rectangular greenhouse. Along one wall is a 7-ft storage area and 5 sections for different kinds of plants. On the opposite wall is a 4 ft storage area and 6 sections for plants. All of the sections for plants are of equal length. What is the length of each wall?
7 + 5x = 4 + 6x
7-4 = 6x-5x
3 = x
