Collecting like terms means to simplify terms in expressions in which the variables are the same. In the expression \(5a + 2b + 3a - 6b\), the terms \(5a\) and \(+ 3a\) are like terms, as are \(2b\) ...

expression let's say we have four times the quantity x minus y whatever X and Y are and then plus one and then I'm going to give you as a kind of like part of the problem that X is equal to negative 2 ...

Algebraic expressions can be simplified by collecting like terms. Positive like terms are often written before the negative like terms. When grouping the like terms together, the order does not matter ...
