Question 368042: The perimeter of a pool table is 30 feet. The table is twice as long as it is wide. What is the length "l" of the pool table? Write an equation to model the situation. Then solve the equation for " l "
Thus is what I have 2w+ L = 30 I know w=5 and l=10 I just don't get how to write and solve the equation...

"The perimeter of a pool table is 30 feet" ___ 2L + 2W = 30 ___ 2W = 30 - 2L

"The table is twice as long as it is wide" ___ L = 2W

substituting ___ L = 30 - 2L
