I would say the answer is C, but double check
Well it would be C! so 78-74=4 so they are counting by 4's and 86+4=90 :33
1. 1/5 = x - 9 / x
2. Cross multiply x = 5 (x - 9)
3. Distribute x = 5x - 45
4. Move the variable and change the sign x - 5x = -45
5. Add like terms -4x = -45
6. Divide x = 45 / 4
So the solution is x = 45 / 4 or 11.25
36 I looked it up and it says 36
The answer is in the photo I attached.
