Two linear expressions can be expanded, and then simplified by collecting like terms, if there are any. Linear expressions have no terms with power of 2 or higher. For example, 15x – 4y is a linear ...
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 \(2b\) ...
