Answer 1

They want you to combine the variables. So
−12x4 + 7x3 + 6x4 − 2x3 =
5x3 − 6x4
So you combine the coefficients, not the variable number, for instance -12+6=-6, and then you simply put the variable in the same place it was. You don't do anything else with it except what I just showed you : )
