um well if C would be the X then

Step-by-step explanation: 2 times 2 is four now you have to figure out which number minus 4 is 5 which would be nine then you go back to the 3x part and the only way to get nine from a 4-3 is it would have to be a negetive so then you see that 2 plus seven is 9 or 2 - (-7) is 9 so you find three times - 7 = -2.33333333
