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

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.

For the first question the answer is a, for the second c, for the third d, for the 4th b, for the 5th a
