sorry, this is the right way:
6x+8y=24, 8y(-6x)=2
also, there is another question I'm having trouble with. subject is Calculus.
1. One day, a person went to horse racing area, Instead of counting the number of human and horses, he instead counted 74 heads and 196 legs. Yet he knew the number of humans and horses there. How did he do it, and how many humans and horses are there?
thanks =)
Add the two equations together
6x+8y=24,
8y-6x=2
16y=26 then find y
subtract the two
12x=22 then find x
