Answer 1

Here we should create system:

where x - amount of calories burned playing basketball for 1 hour

y- amount of calories burned while canoeing for 1 hour

x+2y=1600

2x+3y=2700

express x through y

x=1600-2y and put that in the second equation

2(1600-2y)+3y=2700

3200-4y+3y=2700

y=500

x=1600-1000=600

x=600

y=500
