I did Q= 176.7 (change in energy) + 67 (amount of work done) I got 243.7 What am I doing wrong

I am so lost with this question. Can anyone help? The internal energy of the gas in a gasoline engine's cylinder decreases by 176:7 J. If 67.0 J of work is done by the gas, how much energy is transferred as heat? Answer in units of J
