(f+g)(x) is simply saying add these two problems together.
(2x+6) + (4x^2)
Parenthesis are now useless, as there is only addition.
2x + 6 + 4x^2
Reorder, cause it's pretty and familiar
4x^2 + 2x + 6
We could further simplify
2(2x^2 + x + 3)
A
I would choose the first system to stay the same because it would easier to multiply than divide (something along those lines)
b
if you choose the first system) you would multiply the 2nd equation by a -5
Answer: y = -13/2 = -6.500
so, only one
