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

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?
