use given to get gfw.
36/.1503= {the 36 if from C=1283 and 15.03 comes from % given} then equals to 239.5gfw
(gfw) * (% unknown){unknown 100-15.03}
so, 239.5 * .8497 = 203.5 then divide by 4 because of the X4 = 50.875 about 50.9 V-Vanadium.
Answer: V4C3. is this correct ?????
The compound X4C3 contains 15.03% carbon. What is the chemical symbol for X ?

You would have done well ato just type the question. As it is I don't know where the 36 comes from (you say it is 1283*15.03% but that doesn't tell me where the 1283 comes from.) Nor the 239.5. You answer is plausible but I can't say it is right or wrong.
