Noam solved the equation for k using the following calculations.
k - 7.6 = 10.35
+ 7.6 + 7.6
k=17.41
what error, if any, did he make?
1. he should have subtracted 7.6 instead of adding it.
2. he should have subtracted 10.35 from both sides.
3. he made a computation error when he added 10.35 + 7.6
4. he made a computation error when he added -7.6 and 7.6
