Question

Can you help me add?
8 + x-1/x+4

Answer 1

Multiple Choice:
9x + 31/x+4
7 + x/x+4
8x-8/8x + 32
9x + 31/ x-4

Answer 2

7+x/x+4

Answer 3

(8 + x - 1) / (x + 4)

You can only add numbers to numbers, not numbers (like "7") to variables (like "x") :
So, from numerator : 8-1 = 7

(7 + x) / (x + 4)

Answer is the second one
