You know that we have to simplify the algebra equation, so first you have to combine x and 2x. X + 2x equals to 3x. Now that we combined x and 2x which makes 3x, we have to do 7 and -8. 7 + -8 which equals to -1. Therefore, the answer to this algebra equation is 3x + -1.
I dont know if those lines were suppose to be there, but i put 0.63 in simplest form = 63/100
F(3)=16 i saw this problem before so it should be the answer in the end
