Can you guys help me solve this problem I dont know why I cant get it. Thanks.

Solve for x.
(26000-x)2813.95 + x(314.73)=26000(640.2)

I don't know why you can't get it either, especially since you didn't show your work ...

(26000-x)2813.95 + x(314.73)=26000(640.2)

73162700 - 2813.95x + 314.73x = 16645200
73162700 - 2499.22x = 16645200
2499.22x = 56517500
x = 22614.05559
