How to solve this??? The attendance at the game on two successive nights of Oakland A's baseball was 77,000. The attendance on Thursday's game was 7000 more than two thirds of the attendance at Friday nights game. How many people attended the baseball game each night?

x = attendance at Friday's game
2/3 x + 7000 = attendance at Thursday's game
x + 2/3 x + 7000 = 77000
Solve for x  Fri
2/3 x + 7000  Thur 
the attendance on the first night of a play was 435. The attendance of on the third night was 545. if the attendance increase at a linear rate, then how many people can be expected to show up on the 6th night
