Question

32k-26k+k=?what is the answer to this?

Answer 1

If you are having trouble adding and subtracting variables with coefficients, just pretend like there isn't a variable there.

32-26+1=?

If you subtract 32-26, your answer is 6.

6+1=?

7 is your answer.

However, because we eliminated the variables before, now we have to add them back in, so your answer would be 7k.
