Answer:
x= -23/3 If asked as a decimal, then you would get -7.6 repeating. If it isn't asked to be a decimal just leave it as a fraction, it cannot be reduced or get any simpler. You may pass with -7 2/3. (I would leave it though)
Explanation:
You need to isolate the x by dividing the 3 using inverse operations. you would then be able to just write it out like this:
3x-23 solve for x
3x/3=-23/3
x=-23/3
(Sorry if this didn't help.)
