50+20x=100+10x
; x=5
; after 5 days the prices are equal
50 plus 20 x equals 100 plus 10 x ; x equals 5 ; after 5 days the prices are equal
50+20x=100x+10
; x=1
; after 1 day the prices are equal
50 plus 20 x equals 100 x plus 10 ; x equals 1 ; after 1 day the prices are equal
50x+20=100x+10
; x=5
; after 5 days the prices are equal
50 x plus 20 equals 100 x plus 10 ; x equals 5 ; after 5 days the prices are equal
20x−50=10x−100
; x=−5
; after 5 days the prices are equal
The correct equation is 50 + 20x = 100 + 10x. The solution to this equation is x = 5.
This means that after 5 days, the rental car prices for Rental car A and Rental car B are equal.
