b) \( 4 a-2 b-6 a-5 b= \)

When simplifying the expression \( 4a - 2b - 6a - 5b \), you can start by grouping like terms. Combine the \( a \) terms: \( 4a - 6a = -2a \), and then combine the \( b \) terms: \( -2b - 5b = -7b \). So, the final simplified expression is \( -2a - 7b \). Now you've got an expression that's telling a clear story about the relationship between \( a \) and \( b \)! Remember, keeping your variables organized makes it much easier to see what's happening as you solve equations. Whether it's in algebra or programming, managing your variables well gives you a huge advantage.
