Noam solved the equation for k using the following calculations.
k minus 7.6 = 10.35. + 7.6. k = 17.41.
What error, if any, did he make?
He should have subtracted 7.6 instead of adding it.
He should have subtracted 10.35 from both sides.
He made a computation error when he added 10.35 + 7.6.
He made a computation error when he added negative 7.6 and 7.6.
