Answer:
These features include vegetation, climate, the local water cycle, and land formations. Geography doesn't just determine whether humans can live in a certain area or not, it also determines people's lifestyles, as they adapt to the available food and climate patterns.
Make equations first
Consider bigger number is X and smaller number is Y
condition 1,
3X+3Y = 34----------eq 1
condition 2,
2X-5Y = 9-------------eq 2
multiply eq 1 by 2 and eq 2 by 3,
6X+6Y = 68
6X-15Y = 27
Substracting above equation,
21Y = 41
Y = 41/21
Substituting Value of Y in eq 1,
3X+3×41/21 = 34
3X = 34-41/7
3X = (238-41)/7
3X = 197/7
X = 197/21
Hence X = 197/21 and Y = 41/21
