There are eight, if I'm understanding the question correctly. 8 is in the ten thousands place, at least
2x + 2y must equal 24. 24 - 2x = 2y and 24 - 2y = 2x. Therefore, 12 - y = x. x could be able to add with y to get 12.
example: x = 4, y = 8. (4 + 4 + 8 + 8 = 16 + 8 = 24)
x = 9, y = 3. (9 + 9 + 3 + 3 = 24)
x = 5, y = 7. (5 + 5 + 7 + 7 = 24)
When given a function and asked to find the value of a number, in this case g(12), simply plug 12 into all x places in the equation:
g(12)=3(12+8)
g(12)=36+24
g(12)=60
