From the question:
3b+2g=22
2b+3g=23
we add up the equations:
5b+5g=45
divide by 5:
b+g=9
So the combined mass is 9 grams.

Get the total cubes you need and then subtract the given data (Example: Georgia has 30 apples in all. She has 10 red apples. So there is 20 apples left.). Then get the other given data ( Example: the number of green apples is 9 times the number of granny smith apples.). Then times it by a number (Example: 9x2=18 so there are 18 green apples and there are 2 granny smith apples, which equal 20 apples).
