Can you combine positive and negative like terms together? If so, can you explain how? That would be amazing.

What do you mean by "combine" ?
addition? subtraction? multiplication? division?

If you have something like
12k - 5t - 8k + 13t
we could arrange them
12k - 8k + 13t - 5t, most people do this mentally

= 4k + 8t
I added the coefficients of the like terms (combine ?)
12 + (-8) = 4
13 + (-5) = 8

12 apples take away 8 apples = 4 apples
you have $12 and you lose $8 in a game, you now have $4
12k - 8k = 4k

If you know how to add and subtract integers, then you know how to "combine" like terms.
Thank you
But what I meant by combine like terms, was to combine equations. Ex: 5x+7 and 6x+21 make 11x+28. But only, what if the equations had a negative and a positive. Ex: 4x+5 and 6x-10. How would I combine them?
