3 similar apples and 5 similar oranges have a mass of 270 g. 3 such apples and 7 such oranges have a mass of 342 g. What was the mass of one orange?
Answered by PsyDAG
3A + 5O = 270

3A + 7O = 342

Subtract first equation from the second and work it from there.

To solve the problem, let's use the method of elimination:
3A + 5O = 270
3A + 7O = 342

Subtracting the first equation from the second, we get:
2O = 72
O = 36

Therefore, one orange has a mass of 36g.
