2 car + 2 train = 1280 rs

Car + bear + train = 820 rs

Train - car = 140rs

2 car + 2 bear = ?

1280:2=640

820-640=180

(640-140) : 2=500 500:2=250 (250+140) - 250

500+360=860

2 car + 2 bear = 760

Step-by-step explanation:

if car + bear + train = 820,

then 2cars + 2bears + 2trains = 1640

- 2cars + 0 + 2trains = 1380

2bear = 260

2train - 2car = 280

- (2train+2car) = 1280

-4car=-1000

2car = 500

2 car + 2 bear = 760
