You determine which one to use by seeing which one would be easier

elimination: 5x + 7y = 2
                  -5x + 6y = 6

substitution: y = 9x + 5
                  2y = 7x + 2

5 divided into 290 show work
Archy [21]
How many times does 5 go into 29? It can go into it 5 times which equals 25. Now what's 29 - 25? 4 is the answer then you see how many times can 5 go into 4, well it can't so then you bring the number 0 to make it 40. Now how many times can 5 go into 40? It can go into 40 eight times since 8x5=40 so the answer is 58
