What are two problems associated with the use of solar energy?

Actually, there are a lot of problems associated with the use of solar energy but would like to highlight at least two. The first one that hampers the use of it is its cost. The second one is land use and habitat loss, water use, and the use of hazardous materials in manufacturing.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
