The x=16 because you gotta subtract x one one side to make it a simple two step equation then to simplify x from 5x divide by 5 on both sides
<span>There are 4 long rows and 5 short rows in the theater. x represents the number of chairs in each long row and y represents the number of chairs in each short row.
So, total number of chairs in 4 long rows= 4x
Total number of chairs in 5 short rows = 5y
Total number of chairs in the theater on a normal day = 4x + 5y
When 2 chairs are added to each long row, the number of chairs will change to (x+2).
So, total number of chairs in 4 long rows will be = 4(x+2)
When 3 chairs are added to each short row, the number of chairs will change to (y+3)
So, total number of chairs in 5 short rows will be = 5(y+3)
Thus, total number of chairs in the theater in rush day = 4(x+2) + 5(y+3)
= 4x + 8 + 5y + 15
= 4x + 5y + 23
Thus we can say the number of chairs increase by 23 as compared to a normal day.

Answer:
Last year’s price = $2.96
Step-by-step explanation:
Given:
Current price of gasoline = $3.40
Higher rate = 15%
Find:
Last year’s price
Computation:
Last year’s price = Current price of gasoline [100 / (100 + 15)]
Last year’s price = Current price of gasoline [100 / (115)]
Last year’s price = $3.40 [100 / (115)]
Last year’s price = 2.95652
Last year’s price = $2.96
