You add or subtract it for instance: 14x+258-52. You have to subtract 52 from 258 because of the symbol (-) in front of it. Since there is no other numbers with variables 14x is left alone. Hope this helps

You combine like terms if there are any on either side of the equal sign

Example: 4x + 3x + 5 = 8x + 2 + 3x

4x + 3x = 7x

7x + 5 = 8x + 2 + 3x

8x + 3x = 11x

7x + 5 = 11x + 2 <-- that would be the equation once all like terms are combined
