X/4 is the same as 1/4x, so you have the equation 1/4x + 7 = 5. subtract 7 to both sides to get the equation 1/4x = -2. then you multiply by four (which is the same as dividing by 1/4) to get x = -8

Answer is D & C
Explanation: I did this
Answer:
39x-7
Step-by-step explanation:
The perimeter is all the sides added together so
9x + 8x - 2 + 5x + 1 + 17x - 6
Since you can't solve it you just want to simplify the equation, add the like terms together
9x+8x+5x+17x = 39x
-2+1-6 = -7
Your equation is 39x-7
