ok i should learn how to read
it says total of 60 minutes
and burn 500 calories

if you put $x$ and the number of minutes biking and $y$ as the number of minutes hiking, then the total being 60 gives and equation of $x+y=60$ and burning 500 calories tells you $$10x+7y=500$$

anonymous · Answer

so one system would be $$x+y=60\10x+7y=500$$

anonymous · Answer

you can try it again with different activities, get a similar answer
one equation will always be $x+y=60$ the other will change

SO ONE OF MY EQUATIONS WOULD BE 10X+7Y=500? @satellite73
