5 .... Hope it helps, have a good rest of the day:)
Ok so this is how you do it.....
You need to get x by itself.
8x + c = k
Subtract c.
8x = k - c
Divide 8 from both sides.
x = k - c / 8
I hope this helps love! :)
The answer is C. Since 414 is an even number, it is divisible by 2. Since 115 ends in 5, it is divisible by 5. And 273 is divisible by 3 (if you add all the digits and that number is divisible by 3, so it the originals. 2+7+3=12 12/3=4)
